Q2) Pelton wheel
A) Power produced by a Pelton wheel is (596.8*10'Watt) under a head of (150 m) with wheel rotating
speed equal to (360 r.p.m), the efficiency overall is (85%) and assumption of velocity coefficient is
(0.985), velocity ratio is (0.46). Find
1- Diameter of the wheel
2- Diameter of the jet
3- Discharge
B) A Pelton wheel having velocity of flow equal to (65m/s) and linear velocity is (25m/s). If the angle
between linear velocity, and absolute relative velocity at exit 20°, Friction coefficient blade is (0.9) and
volume flow rate is (0.9 m'/s). Determine
1- Production Power in (kWatt)
2- Effeciency of Hydraulic
Hint: vou must plot velocity triange to solve the problem
