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?

Chemical Engineering Fluid Mechanics 30. The purpose of a centrifugal pump is to increase the pressure of a liquid in order to move it through a piping system. The pump is driven by a motor, which must provide sufficient power to operate the pump at the desired conditions. You wish to find the pressure developed by a pump operating at a flow rate of 300 gpm with an oil having a specific gravity (SG) of 0.8 and a viscosity of...
