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.
ESFR vs. Conventional Sprinklers. ESFR (Early Suppression Fast Response) sprinkler systems are designed to achieve fire suppression for a specific type of storage occupancy before the fire becomes fully developed. ESFR heads vary with K-factors of 11.2, 14.7, 17 and 25.2 with as well as pressures of 50 and 70 psi.
