Question
The 600 mm diameter pipe conducts water from reservoir A (El. 61 meters) to a pressure turbine (El. 4.60 meters), which discharges through another 600-mm diameter pipe into tailrace B (El. 0 meter). The loss of head from A to the entrance of the turbine (pt.1 ) is 5 times the velocity head in the pipe and the loss of head from the exit of the turbine (pt.2) is 0.20 times the velocity head in the pipe. If the discharge is 708 Liters/second, Determine the efficiency of the turbine if the output power is 480 hp. a. 61.20% b. 69.15% c. 75.72% d. 86.88% e. 89.57%
