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?
A perfect venture with throat diameter of 1.8 inches is placed horizontally in a pipe with a 5 in inside diameter. 80 lb of water flow through the pipe each second. What is the difference between the pipe and venture throat static pressure?
