Hydro-electric power is to be generated by installing a hydraulic turbine-generator combination 400 ft below the free surface of a reservoir. If combined turbine-generator efficiency is 85%, frictional energy losses in the piping are 36 ft, and the electrical power output is 100 kW,
a) flow rate in lbm/s
b) flow rate in ft3/s
