Apump takes water from the bottom of a large tank where the pressure is 50 psig and delivers it through a hose to a nozzle that is 50 ft above the bottom of the tank at a rate of 100 lbm/s. the water exits the nozzle into the atmosphere at a velocity of 70 ft/s. if a 10 hp motor is required to drive the pump, which is 75% efficient, find:
a) the friction loss in the pump;
b) the friction loss in the rest of the system.
express your answer in units of ft lbf/lbm.
