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.
Check the valves. Check the valves on the backflow device to make sure they're open. Turn the valve on the horizontal pipe first, then the vertical pipe valve. Low water pressure will result in the sprinkler heads barely shooting water.In extreme cases, many of the heads won't even pop up. Start with the easiest solution.heck the valves.
