Determining the average velocity in the pipe

Assignment Help Other Engineering
Reference no: EM13879268

Water at 20°C is pumped at 1500 gal/min from the lower to the upper reservoir, as in Fig. P3.141. Pipe friction losses are approximated by hf ˜ 27V2 /(2g), where V is the average velocity in the pipe. If the pump is 75 percent efficient, what horsepower is needed to drive it?
