Water flows from Reservoir A (Elev 125 m.) to a turbine (Elev 67 m.) then discharges into tailtrace B (Elev 26 m.) as shown. The head loss from (A) to (1) is 2 times the velocity head in the pipe, and the head loss from (2) to (b) is 1.97 times the velocity head in the pipe. If the flow rate in the pipe is 39 ft3/s, diameter of all pipes is 30 in, calculate the horsepower generated by the turbine. Use 1 hp = 550 lb-ft/s.
