Question: P r 2 ( 5 0 pt ) : The 1 7 in impeller diameter pump given below, operating at 1 7 7 0 rpm

Pr2(50 pt): The 17 in impeller diameter pump given below, operating at 1770 rpm is to pump 3500 gpm of water at 68F in the system shown below. The total length of pipe is 1500 ft with 500 ft on the suction side and 1000 ft on the discharge side and the inner pipe diameter is 10 in . The surface of the left tank is Z1=100ft There are two 90 deg regular elbows (K=1.5, both downstream of the pump), and entrance )=(0.8 and exit )=(1.0 losses. The absolute roughness for cast iron is 0.00085 ft . The density of the water is 68F62.3lbmft3, and the dynamic viscosity is =6.55610-4lbmft-s.
(a)(5 pt) Compute the minor friction losses.
(b)(5 pt) Compute major friction losses
(c) pt) What is the head delivered by the pump?
(d)(10 pt) Determine the value of z2.
(e)) Compute the power delivered to the water by the pump.
(f)(5 pt) Compute the power supplied by the motor.
(g)(5 pt) What is the NPSHr for the pump for the flow condition.
(h)(10 pt) If the water is at 150F instead of 68F, what is the NPSHa at the pump inlet. Assume the left tank is at atmospheric pressure and the inlet line to the pump is at z=25ft. Will cavitation occur at the inlet to the pump? Give all calculations to support your answer.
