Question: For the situation sketched, find the required power input to the fluid from the pump.
2. A 25-hp pump is employed to deliver an organic liquid (p=50 lbm/ft3) through a piping system, as shown. Under the existing conditions, the liquid flow rate is 4,488 gaymin.
a. Calculate the frictional losses ("lost work") in the piping system between points 1 and 2 in ft lbf/s.
b. Assuming that the frictional losses vary as the square of the flow rate, calculate the required pump horsepower if the delivery rate is to be doubled.
