In a hydroelectric power plant, water flows from an elevation of 400 ft to a turbine, where electric power is generated. For an overall turbine-generator efficiency of 82 percent, determine the flow rate of water to generate 100 kW of electricity if the irreversible head loss of the piping system between the free surfaces of the inlet and the outlet is 36 ft. Take the density of water to be p = 62.4 lbm/ft³. The flow rate of water is 0.151 ft³/s.

14A fluid flows at a speed of 7.5 m/s in a pipe with a diameter of 35 cm. What is the power, in W, of the pump to overcome the irreversible pressure drop when the pressure drop along the pipe is calculated to be 6300 Pa?
A river flowing steadily at a rate of 125 m3/s is considered for hydroelectric power generation. It is determined that a dam can be built to collect water and release it from an elevation difference of 70 m to generate power. Determine how much power can be generated from this river water after the dam is filled.
Electric power is to be generated by installing a hydraulic turbine—generator at a site 120 m below the free surface of a large water reservoir that can supply water steadily at a rate of 930 kg/s. If the mechanical power output of the turbine is 850 kW and the electric power generation is 770 kW, determine the turbine efficiency and the combined turbine— generator efficiency of this plant. Neglect losses in the pipes.
A compressor is to be used to draw air from the outdoors where the conditions are 26.5 C and 100.04 kPa. The desired volume flowrate is 0.28 cubic meter per second. The air will pass through a duct with a diameter of 14 cm. The vertical height of the duct is 11.7 m. If the efficiency is 88.0 %, determine the required power in W. Assume a friction factor of 0.023.
