Got a calculation I'm reviewing where the designer used the fire pump 50% test point for his calculations and plugged it in as the City water supply info. The water source for the fire pump is an aboveground suction tank.
I've not done this and was always taught that when a fire pump was used you used the fire pump churn, rated and 150% values in the calculation for your water source. Any thoughts, did I miss a memo on a new or other way to calc when using a fire pump? Craig L.
