This course is designed for wildland firefighters. This is almost never the case, but different pumps and speeds affect the churn pressure, so you should always look at a curve to determine the shutoff pressure.Topics include calculating tank volumes and flow rates, determining pump pressure and friction loss, understanding maps and location coordinates, and estimating slope.ДЄdditionally, the course presents information on calculating flame length, flame height, midflame windspeed, and other variables related to wildland firefighting efforts. One thing that some engineers forget is that the pump will discharge at a much higher pressure at churn no flow than at the design point. However, the friction loss and pipe sizing become an issue when doing this calculation, which is why most contractors and sprinkler designers use software. A similar calculation can be used for a non-high rise, by changing the psi to the end head pressure 15 - 50 psi, depending on the head. Assume that the pump is 1, gpm for this example.ДЄs you can see, the calculated required pump psi is psi. If you use a calculation sheet, a few variables need to be filled in. When calculating the water pressure for a high rise, it is a good idea to use a calculation sheet such as the one shown in Figure 2. These programs are used by sprinkler contractors to keep their pipes as small as possible, which controls the cost of the job.

This discussion concentrates on high rises because the pressure calculations for most non-high-rise buildings are determined through the use of software specifically designed for fire sprinkler hydraulic calculations. This is a factor because any high rise requires a pressure of pounds per square inch psi at the top of the structure while flowing the rated gallons per minute gpm of the fire pump. One is for high-rise structures buildings greater than 75 feet in height, measured from the lowest level of fire department vehicle access to the floor of the highest occupiable story and one is for non-high-rise structures. Two types of structure calculations for pressure are available. In any case, the demand of the system will dictate the pressure and flow required. The last job parameter you need in order to size the fire pump is the required flow for the systems the pump will be serving sprinklers, standpipes, or other.ДЇor standpipe systems, this flow is related to the type and size of the structure the pump is protecting. Thus, if the water supply is located below the suction inlet to the fire pump, you may have to utilize a vertical turbine fire pump in lieu of the other types of pumps available. If you are using a private water supply, lake, or ground-level storage tank, you must remember that you are not permitted to use a suction lift with a fire pump. If not, request a new test using more hydrants or plot a water supply curve see Figure 1. This will ensure that the municipal supply will provide enough volume to meet the system demand. Another consideration regarding the water test is this: Did the city flow enough water to meet percent of the fire pump design point? Additionally, in highly residential areas, peak morning use typically occurs early in the day, between and 9 a. In a cold climate, testing during the summer may be a better choice, since residents are watering their lawns and commercial properties are using more water for cooling. If you are utilizing the city water supply as the primary source for the pump, you need to make sure that an accurate city water test is used. When starting a fire pump design, the most important item to consider is the water supply.
