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.
One atmosphere (101.325 kPa or 14.7 lbf/inÂ²) is the amount of pressure that can lift water approximately 10.3 m (33.9 feet). Thus, a diver at a depth 10.3 meters under water in a fresh-water lake experiences a pressure of about 2 atmospheres (1 atm for the air and 1 atm for the water).ne atmosphere (101.325 kPa or 14.7 lbf/inÂ²) is the amount of pressure that can lift water approximately 10.3 m (33.9 feet).
