The driving force for fluid flow is the pressure difference, and a pump operates by raising the pressure of a fluid (by converting the mechanical shaft work to flow energy). A gasoline pump is measured to consume 31 kW of electric power when operating. If the pressure differential between the outlet and inlet of the pump is measured to be 5.9 kPa and the changes in velocity and elevation are negligible, determine the maximum possible volume flow rate of gasoline.
