A Pelton wheel has to develop
18000 B.H.P under a net head
of 800 m, while running at a
speed of 600 rpm. If the
coefficient of the jet=D0.97,
speed ratio= 0.46 and the ratio
of the jet diameter is 1/15 of
wheel diameter, assume overall
efficiency as 85%. Calculate the
.diameter of the pitch circle
