It is decided to install several single-jet Pelton wheels to produce a total power of 18 MW. The
available head is 246 m. The wheel rotational speed is 650 rpm and the speed ratio (❤) = 0.46.
The diameter of the nozzle (jet) is limited to be 0.167 m with a Cv of 0.95. The efficiency of each
turbine is 87%. Determine: (1) The number of Pelton wheels to be used, and (2) The bucket
angle.
