Extracted text: . water at 20°C is to be pumped from reservoir 1 to 2 in a 6-in-diameter asphalted cast iron pipe at V = 6 ft/s. With 80 percent pump efficiency, the required power is 4.10 hp. What is he proper pipe length to match these conditions? Under the given flow condition, water properties are:p=1.94 slug/ft³ and u = 2.09E - 5 slug/ (ft s). For asphalted cast iron, e = 0.0004ft. 20 ft Pump
