This configuration uses a main pipe that branches out into smaller pipes, similar to how a tree has branches that grow from its trunk. The piping layouts of most fire protection systems can be classified into three main types, based on how individual pipes are arranged: tree, loop, and grid. This must be considered in the hydraulic calculation procedure, and the pressure boost can be achieved with a fire pump or pressurized tank. When water is obtained from a static source like a lake or buried tank, additional pressure is required for effective fire protection. Underground, above-ground and elevated water tanks are examples of closed sources.Lakes, ponds and rivers are examples of open sources.When this happens, the piping can be designed to draw water from other sources, which can be classified as open or closed: There may be cases in which the municipal water supply is insufficient for fire protection, or not available. This can be accomplished by measuring pressure and flow at a water hydrant, but this information may also be available publicly from the municipal water department. How Much Water Is Required for Fire Protection?Ī water flow test is required before starting a hydraulic calculation. If you are developing commercial spaces for rent, reliable fire protection is also a valuable feature for potential tenants.

Get a professional fire sprinkler design for your next building project.Īn adequate fire protection design safeguards your building and its occupants. What is the optimal layout of the piping system, and what friction losses are produced?.If a fire occurs, how much water is required to extinguish it?.The hydraulic calculation procedure deals with three very important aspects of a fire suppression system: In particular, automatic sprinkler systems are subject to the NFPA 13 Standard in the US, and the equivalent international standard is EN 12845. Hydraulic calculations are very important when designing fire protection systems, since they ensure that the piping delivers enough water to extinguish any fire.
