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? QUESTION...
The rotor shown below rotates with an angular velocity of 2000 rpm. Assume that the fluid enters in the radial direction and the relative velocity is tangent to the blades across the entire rotor. Find the exit normal velocity (ft/s) and exit velocity of the blade in terms of inlet. Draw the inlet and outlet velocity triangles. Is the device a pump or a turbine? Explain. Hint: create a velocity triangle at (1) and (2) and compare them. Does the...
