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.
Instead, we have to look at both water pressure and the resulting functional flow. Water pressure is the amount of force from the water main into your home. Water pressure is measured in pounds per square inch (PSI), and normal water pressure is typically between 30 and 80 PSI. Functional flow is the volume of water flowing through your pipes and arriving at individual fixtures. Poor functional flow may be due to buildups in the pipes or poor plumbing.
