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.
My water pressure is less than 10 psi (7 or 8 psi). I wonder if I can run sprinkler valves without a booster pump. I read somewhere on internet that these valves need some pressure for proper operation, especially closing. By the way, I am going to use microirrigation (drip). 7 psi can run several small emitters without a problem according to emitter manuracturer's website. Any information would be much appreciated.
