Problem 3: A submersible deep-well pump delivers 745 gal/ h of water through a 1-in Schedule 40 pipe when operating in the system sketched in the figure below. An energy loss of 10.5 lb-ft/lb occurs in the piping system. (a) Calculate the power delivered by the pump to the water. (b) If the pump draws 1 hp, calculate its efficiency.

No. 1: A water system of 2 inches (inside diameter) pipe, having a length of 1/4mile, is to be flushed with a volume of water equal to twice that contained in the system. How much water (number of gallons) must be flushed through the system. (1ft3 = 7.481 gallons)
Problem 2. Water at 150°F is pumped at the rate of 60 gal/min from a reservoir at atmospheric pressure. The gauge pressure at the end of the discharge line is 42 psi. The discharge point is 12 ft above the level is the reservoir and the suction line is 6 ft above the level of the reservoir. The discharge line is a 1 ½ in. nominal dimeter steel pipe with a schedule number of 80. The pressure drop due to friction in the suction line is known to be 0.8 psi, and that in the discharge line is 7.2 psi. The mechanical efficiency of the pump is 70%. Calculate (a) the developed head of the pump and (b) the total power input. (c) If the pump manufacturer specifies a required NPSH of 8 ft, will the pump be suitable for this service?
