A two-jet Pelton wheel produces power of 2 MW at 400 rpm. The diameter of the wheel is 1.5 m.
The gross head (i.e., measured from the water surface in the reservoir to the nozzle) is 200 m.
Consider the head loss in the penstock and nozzle is 10% and the deflected velocity by the bucket
is reduced by 10% due to friction. Given that the deflected angle is 165° and the nozzle efficiency
is 0.95, determine
a) Nozzle head,
b) Euler head,
c) Velocity ratio,
d) Diameter of the jet,
e) Wheel power, and
f) Mechanical efficiency.
