A fluid with density 114.8 lb/ft3 is to be pumped from a reservoir to an elevation 50 ft higher. The inner diameter of the piping is 2.067 inches on both sides of the pump and the volumetric flow rate of the fluid is 69.1 gal/min. Friction losses for the piping amount to 10 ft lbf/lb. Determine the horsepower required for the pump if it is 65% efficient. Hint: Take position 1 to be the surface of the reservoir and assume the reservoir surface is very large compared to the pipe diameter. Take position 2 to be the outlet from the pipe at 50 ft elevation
