Question

Calculate the mechanical power [hp] required on the pump shaft considering the hydraulic system 
Shown. The pipe is made of commercial steel (roughness = 0.0002 ft) and has two different diameters, 
up to the pump inlet the pipe is 2 inches with a length of 100ft and from the pump outlet the pipe is 4 inches with 400ft. All elements are screwed The flow rate circulating through the system is 0.5 ft3/s and the efficiency of the pump is 85%. The density of water is 1.94 slug/ft3 and has a viscosity kinematics 1.1x10-5 ft2/s
