Fire Sprinkler Systems Basics




Before we dive into the details of fire sprinkler systems layout and calculation, let's first review some basic concepts about fire sprinkler systems. What are they, how do they work, and what are the different types and components?


Types of Fire Sprinkler Systems




Fire sprinkler systems are classified into different types based on their water supply, activation mechanism, piping arrangement, and coverage area. Some of the most common types are:



  • Wet pipe system: This is the simplest and most widely used type of fire sprinkler system. It consists of a network of pipes filled with pressurized water that is connected to sprinkler heads. When a fire is detected by a heat-sensitive element in the sprinkler head, it opens a valve that releases water onto the fire.



  • Dry pipe system: This type of fire sprinkler system is similar to the wet pipe system, except that the pipes are filled with pressurized air or nitrogen instead of water. This prevents the pipes from freezing in cold environments. When a fire is detected by a sprinkler head, it opens a valve that allows water to flow into the pipes and then onto the fire.



  • Pre-action system: This type of fire sprinkler system is designed to prevent accidental water discharge due to false alarms or mechanical failures. It consists of a network of pipes filled with pressurized air or nitrogen that is connected to a water supply through a pre-action valve. The pre-action valve is controlled by a separate fire detection system that uses smoke or heat detectors. When a fire is confirmed by the detection system, it activates the pre-action valve that allows water to flow into the pipes and then onto the fire.



  • Deluge system: This type of fire sprinkler system is used for high-risk areas where a large amount of water is needed to suppress a fire quickly. It consists of a network of pipes that are connected to open sprinkler heads and a water supply through a deluge valve. The deluge valve is controlled by a separate fire detection system that uses smoke or heat detectors. When a fire is confirmed by the detection system, it opens the deluge valve that allows water to flow into the pipes and then onto the fire.



Components of Fire Sprinkler Systems




Fire sprinkler systems consist of various components that work together to provide fire protection. Some of the main components are:



  • Water supply: This is the source of water that is used to extinguish the fire. It can be a public water main, a private water tank, a reservoir, a lake, or a river. The water supply must have adequate pressure and flow rate to meet the demand of the fire sprinkler system.



  • Pump: This is a device that boosts the pressure and flow rate of the water supply to meet the requirements of the fire sprinkler system. It can be electric, diesel, or gas-powered.



  • Pipe: This is the conduit that transports water from the water supply to the sprinkler heads. It can be made of steel, copper, plastic, or other materials. The pipe size and layout depend on the type and design of the fire sprinkler system.



  • Sprinkler head: This is the device that distributes water onto the fire. It can be fixed, pendant, upright, sidewall, or concealed. The sprinkler head has an orifice that determines the flow rate and spray pattern of the water. It also has a heat-sensitive element that triggers the opening of the valve when exposed to a certain temperature.



  • Valve: This is a device that controls the flow of water in the fire sprinkler system. It can be manual, automatic, or both. Some of the common types of valves are isolation valve, control valve, check valve, alarm valve, pre-action valve, and deluge valve.



  • Alarm: This is a device that alerts the occupants and authorities of a fire event. It can be audible, visual, or both. Some of the common types of alarms are bell, horn, strobe light, and speaker.



Design Standards and Codes for Fire Sprinkler Systems




Fire sprinkler systems must be designed and installed according to certain standards and codes that ensure their safety and effectiveness. Some of the most widely recognized standards and codes are:



  • NFPA 13: This is the standard for the installation of sprinkler systems published by the National Fire Protection Association (NFPA). It covers all aspects of fire sprinkler systems design, installation, testing, and maintenance.



  • NFPA 25: This is the standard for the inspection, testing, and maintenance of water-based fire protection systems published by the NFPA. It covers all types of water-based fire protection systems, including fire sprinkler systems.



  • NFPA 101: This is the code for life safety from fire in buildings and structures published by the NFPA. It covers all aspects of building design, construction, operation, and maintenance that affect life safety from fire.



  • IBC: This is the International Building Code published by the International Code Council (ICC). It covers all aspects of building design, construction, and occupancy that affect public health and safety.



  • NBC: This is the National Building Code published by the Canadian Commission on Building and Fire Codes (CCBFC). It covers all aspects of building design, construction, and occupancy that affect public health and safety in Canada.



Fire Sprinkler Systems Layout and Calculation




Now that we have reviewed some basic concepts about fire sprinkler systems, let's move on to the details of fire sprinkler systems layout and calculation. How do you plan and design a fire sprinkler system? What are the principles and methods for layout and calculation? What are some examples and case studies?


Layout Principles and Methods for Fire Sprinkler Systems




The layout of a fire sprinkler system is the process of determining the location, size, type, and arrangement of pipes, valves, sprinkler heads, pumps, alarms, and other components in a building or structure. The layout must comply with the applicable standards and codes, as well as meet the specific needs and preferences of the owner and occupant.


Layout Principles and Methods for Fire Sprinkler Systems (continued)




The layout method for a fire sprinkler system depends on several factors, such as:



  • The type of fire sprinkler system: Different types of fire sprinkler systems have different layout requirements and options. For example, a wet pipe system can have a simple loop or grid layout, while a dry pipe system may need a more complex layout to avoid air pockets and water hammer.



  • The type of building or structure: Different types of buildings or structures have different layout challenges and opportunities. For example, a high-rise building may need a zoned or multistage layout to overcome the pressure loss and friction loss in the pipes, while a warehouse may need a rack or in-rack layout to protect the stored goods.



  • The fire hazard and occupancy classification: Different fire hazards and occupancies have different layout criteria and specifications. For example, a light hazard occupancy may need fewer and smaller sprinkler heads than an ordinary hazard occupancy, while a storage occupancy may need larger and more closely spaced sprinkler heads than an office occupancy.



  • The aesthetic and functional considerations: Different aesthetic and functional preferences may influence the layout choices and alternatives. For example, some owners or occupants may prefer concealed or recessed sprinkler heads to enhance the appearance of the ceiling, while others may prefer exposed or pendant sprinkler heads to facilitate maintenance and inspection.



Some of the common layout methods for fire sprinkler systems are:



  • Tree system: This is a layout method where the pipes branch out from a main pipe like a tree. It is simple and economical, but it may result in uneven water distribution and pressure loss.



  • Loop system: This is a layout method where the pipes form one or more loops that are connected to a main pipe. It is more balanced and efficient than the tree system, but it may require more pipes and fittings.



  • Grid system: This is a layout method where the pipes form a grid that is connected to one or more main pipes. It is the most balanced and efficient layout method, but it may require the most pipes and fittings.



  • Zoned system: This is a layout method where the pipes are divided into zones that are controlled by separate valves. It is useful for large or complex buildings or structures, but it may increase the complexity and cost of the system.



  • Multistage system: This is a layout method where the pipes are divided into stages that are connected by pumps. It is useful for high-rise buildings or structures, but it may increase the energy consumption and maintenance of the system.



Calculation Formulas and Tools for Fire Sprinkler Systems




The calculation of a fire sprinkler system is the process of determining the required water supply, pressure, flow rate, pipe size, sprinkler head spacing, pump capacity, valve setting, alarm setting, and other parameters for a given layout and design. The calculation must comply with the applicable standards and codes, as well as meet the specific performance and reliability goals.


The calculation formulas and tools for a fire sprinkler system depend on several factors, such as:



  • The type of fire sprinkler system: Different types of fire sprinkler systems have different calculation methods and assumptions. For example, a wet pipe system can use a simplified calculation method based on the hydraulic demand of the most remote sprinkler head, while a dry pipe system may need a more detailed calculation method based on the air-water flow dynamics in the pipes.



  • The type of building or structure: Different types of buildings or structures have different calculation challenges and opportunities. For example, a high-rise building may need to account for the elevation head and friction head in the pipes, while a warehouse may need to account for the obstruction head and k-factor in the sprinkler heads.



  • The fire hazard and occupancy classification: Different fire hazards and occupancies have different calculation criteria and specifications. For example, a light hazard occupancy may need lower water supply and pressure than an ordinary hazard occupancy, while a storage occupancy may need higher water supply and pressure than an office occupancy.



  • The available data and information: Different data and information sources may affect the accuracy and reliability of the calculation results. For example, some data and information may be obtained from the water supply authority, the building owner, the fire sprinkler system manufacturer, the fire sprinkler system installer, or the fire sprinkler system designer.



Some of the common calculation formulas and tools for fire sprinkler systems are:



  • Bernoulli's equation: This is a formula that relates the pressure, velocity, and elevation of a fluid in a pipe. It can be used to calculate the pressure loss or gain in a pipe due to friction, elevation, or fittings.



  • Hazen-Williams equation: This is a formula that relates the flow rate, pipe diameter, pipe length, and pipe roughness of a fluid in a pipe. It can be used to calculate the friction loss or head loss in a pipe due to friction.



  • Darcy-Weisbach equation: This is a formula that relates the flow rate, pipe diameter, pipe length, pipe roughness, and fluid density and viscosity of a fluid in a pipe. It can be used to calculate the friction loss or head loss in a pipe due to friction.



  • Orifice equation: This is a formula that relates the flow rate, orifice diameter, orifice coefficient, and pressure difference of a fluid through an orifice. It can be used to calculate the flow rate or discharge of a sprinkler head.



  • Q=KP equation: This is a formula that relates the flow rate, sprinkler head coefficient, and pressure of a fluid through a sprinkler head. It can be used to calculate the flow rate or discharge of a sprinkler head.



  • Hydraulic calculation software: This is a tool that uses computer algorithms and databases to perform complex and comprehensive hydraulic calculations for fire sprinkler systems. It can be used to calculate all the required parameters and generate reports and diagrams for fire sprinkler systems.



Examples and Case Studies of Fire Sprinkler Systems Layout and Calculation




To illustrate how fire sprinkler systems layout and calculation are done in practice, here are some examples and case studies of real-world projects and applications:



  • Example 1: Wet Pipe System for an Office Building



This is an example of a wet pipe system for an office building with four floors and a total area of 10,000 square meters. The building is classified as an ordinary hazard group 2 occupancy with a design density of 7.5 mm/min and an area of operation of 150 square meters. The water supply is from a public water main with a static pressure of 6 bar and a residual pressure of 4 bar at the base of the building. The design objective is to provide adequate water supply and pressure for the fire sprinkler system.


The layout method for this wet pipe system is a grid system with one main pipe per floor and several branch pipes per main pipe. The main pipes are connected to a riser pipe that runs vertically through the building. The riser pipe is connected to the water supply through an alarm valve that activates an alarm when water flows through it. The sprinkler heads are pendant type with an orifice diameter of 15 mm and a k-factor of 80.


The calculation method for this wet pipe system is based on the hydraulic demand of the most remote sprinkler head on each floor. The calculation tool is a hydraulic calculation software that uses the Hazen-Williams equation for friction loss and the Q=KP equation for sprinkler head discharge. The calculation results are as follows:

Total-------957.6 (12 heads)-


The total water demand for this wet pipe system is 957.6 L/min, which is less than the available water supply of 1000 L/min from the water main. The minimum pressure required at the base of the riser pipe is 1.2 bar, which is less than the available pressure of 4 bar from the water main. Therefore, this wet pipe system is feasible and adequate for the office building.



  • Example 2: Dry Pipe System for a Cold Storage Facility



This is an example of a dry pipe system for a cold storage facility with one floor and a total area of 5000 square meters. The facility is classified as a high-piled storage occupancy with a design density of 12.2 mm/min and an area of operation of 465 square meters. The water supply is from a private water tank with a static pressure of 10 bar and a residual pressure of 8 bar at the base of the facility. The design objective is to provide adequate water supply and pressure for the fire sprinkler system.


The layout method for this dry pipe system is a tree system with one main pipe and several branch pipes. The main pipe is connected to the water supply through a dry pipe valve that holds back the water with pressurized air or nitrogen. The dry pipe valve is controlled by a separate fire detection system that uses smoke or heat detectors. When a fire is confirmed by the detection system, it opens the dry pipe valve that allows water to flow into the pipes and then onto the fire. The sprinkler heads are upright type with an orifice diameter of 20 mm and a k-factor of 115.


The calculation method for this dry pipe system is based on the air-water flow dynamics in the pipes. The calculation tool is a hydraulic calculation software that uses the Darcy-Weisbach equation for friction loss and the orifice equation for sprinkler head discharge. The calculation results are as follows:
