A Pelton wheel is supplied water from a dam which is 200 meters above the centerline of the nozzle of the turbine. The losses in the pipe is 30 meters of water head.

(a) Find the pressure in kPa at the inlet of the nozzle.

(b) If the nozzle velocity coefficient is 0.96 what is velocity at the exit of the nozzle.

(c) If the exit diameter of the nozzle is 150 mm find the flow rate through the nozzle.

(d) If the blade speed ratio is 0.46 find the blade speed of the turbine wheel

(e) If the wheel diameter is 1.5 m determine the rpm of the wheel.

(f) If the relative velocity through the bucket of the wheel is reduced by 10% and the jet is deflected by 1600 find the runner efficiency.

(g) Find the power output from the runner

(h) If the mechanical efficiency is 0.9 find the power output from the turbine.

(i) Find the specific speed of the turbine

(j) If the Thoma number is 0.05 find the net positive suction head of the turbine

(k) Find the suction specific speed of the turbine.
