Water from a large mountain reservoir flows steadily through a steel pipe of 12 in nominal diameter (schedule 40) and effective length of 1500 ft into a turbine where it is discharged to atmosphere. The turbine is 600 ft below the surface of the reservoir. If the water flow rate is 12.5 ft 3 /s, and the turbine produces 425 kW of useful electrical power, estimate the following: (a) The efficiency of the turbine. (b) The pressure at the inlet to the turbine in psig. (c) The power dissipated by pipe friction in kW. (d) The velocity gradient at the pipe wall (viscosity of water=1 cP).
