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.
Without a pressure switch and gauge, the pump would run every time someone opened a water tap and dropped the water in the holding tank or pressure tank even a little. The pressure gauge in most residential systems is set to a maximum of 50 pounds per square inch (PSI) and a minimum of 30 (PSI).
