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.
When water is heated to 120 degrees from an ambient of 52 degrees, how much pressure increase is there inside the hot water tank? How many pounds does the pressure increse in pressure per degree of temperature increase? Also, assuming a pressure regulator installed at the meter, the pressure doesn't flow back to the service line. How much of an issue is the increase in pressure, when the unregulated pressure is 120 psi? Back To Top.
