In the forward flow test, what is the base flow rate specified?

• A. 312 gpm
• B. 500 gpm
• C. 600 gpm
• D. 700 gpm

Answer: (A)

The forward flow test uses a defined base flow rate as the reference point for evaluating the system’s performance. The base flow rate of 312 gpm is specified by the test protocol for this scenario. Keeping the flow at this steady value provides a consistent condition to calculate friction losses, obtain stable pressure readings, and compare results against the pump curve and design expectations. Using a different flow would alter the head losses and pressure readings, making it outside the standard baseline that the test is designed to measure.
