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.
â Insure the jet hose has been placed in the pipe (minimum of 6 feet suggested) before engaging the water pressure. to prevent the hose from coming out of the pipe prematurely and causing injury. â Always shut the water pressure off before pulling the hose out of the pipe. Mark the hose a minimum of 6 feet. from the end to help insure the hose is not accidentally pulled out of the pipe while still under pressure. Shut off the. water pressure when the hose mark is encountered. WARNING: Portions of the system can still be under pressure. even if the unit is not operating.
