A pump is rated at 100 gpm at a 40 oot head with standard water

Customer Question

A pump is rated at 100 gpm at a 40 oot head with standard water (60 degrees, spec. gravity = 1.0). If the pump is circulating 240 degree water (spec. gravity = 0.95) at a head of 40 feet, what will the flow rate be?

Hello, I need to know if this is a test question you need help with or if this relates to a real life situation. The reason I mention this is because pump suction cavitation potential increases dramatically as the water temperature rises, once the pump cavitates the flow rate will drop to zero.
