Question
A two-jet Pelton wheel is required to produce 2MW power with
400rpm. The diameter of the wheel is 1.5m. Gross head measure from
the water surface in reservoir to the nozzle is 200m. Head loss in the
penstock and nozzle is 10% and the deflected velocity by the bucket
reduced 10%. If the deflected angle is 1650, determine;
a) Nozzle head
b) Euler Head
c) Velocity ratio
d) Diameter of jet
