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.
1 Typically this is 20 or 30 psi on a residential water system. 2  On a submersible well pump system the cut-in pressure may be as much as 40 psi. 3  The well pump pressure control switch senses the pressure drop, closes an internal electrical relay switch to turn on the submersible well pump.
