The bachelorâs degree in engineering is a challenging program that requires a substantial amount of coursework in mathematics and natural sciences in addition to the core and elective engineering classes.
Fire Sprinkler Head - Minimum Pressure Requirement. I am reviewing Hydraulic Calculations for a wet type fire sprinkler system to be installed in an existing building. The new sprinkler system will connect to an existing fire pump fed by a 25,000 gallon underground water storage tank (the tank is dedicated to fire protection). From the hydraulic calculations, it appears that the designer is using a minimum pressure of 14 psig at the sprinkler heads located in the Hydraulic remote zone.
The number of sprinklers per zone depends on the pounds per square inch pressure (PSI) and gallons per minute (GPM) flow of the system as well as the gallons per minute used by each sprinkler head.Sprinkler heads use more gallons per minute at higher PSI but can be spaced farther apart.. Measure GPM, or gallons per minute flow, by placing a 5-gallon bucket under the faucet. Turn the faucet on and record how many seconds it takes for the bucket to fill. Calculate GPM by dividing the number of gallons (5) by the number of seconds and multiplying by 60.
