Question

1. What power in kilowatts can be developed by the impulse turbine shown if the turbine efficiency is 85%? Assume that the resistance coefficient fof the penstock is 0.015 and the head loss in the nozzle itself is negligible. What will be the angular speed of the wheel, assuming ideal conditions (r-?.kr. ), and what torque will be exerted on the turbine shaft? Assumptions: there is no entrance loss, head loss in nozzle is negligible, and water density is 1000kg/m (Head loss) h.-f??×?"2 = 001 5x-en-x(0.032).-= 0.094- 6000 2g 2g Elevation- 1670 m Penstock D Im Elevation 1000m 6 km de-18 cm
