Please answer question 7:
A centrifugal pump discharges 500 GPM through a 12-inch diameter
impeller. The fluid leaves the impeller with a
tangential velocity of 17 ft/sec. If water, @ 68°F,
enters the impeller via radial flow (I.E. no whirl), and the inner
radius and thickness of the impeller are
1.75-inches. (Assume a constant thickness of the
impeller) and if the pump speed is 1775 rpm, with a head loss of
4.5-feet. What is the horsepower input to the flow by
the pump?
