Which steps comprise a simple flow test to verify pump performance with a known nozzle?

• A. Set to prescribed PDP
• B. Open nozzle to test
• C. Monitor discharge pressure and flow
• D. All of the above

Answer: (D)

A simple flow test with a known nozzle loads the pump to a defined discharge condition and checks its output by watching pressure and flow as that load is applied. Start by setting the pump to the prescribed discharge pressure (PDP) so you’re testing at the intended operating point. Then open the nozzle to create the expected flow path and load on the pump. Finally, monitor the discharge pressure and the actual flow to verify the pump can maintain the PDP while delivering the expected flow through the nozzle. Doing all three steps ensures the test accurately reflects whether the pump meets the required performance at that known nozzle setting.
