An impulse turbine is used to produce power from an
available head of 500 m and flow rate of 100,000 GPM. Find the diameter of the
jet and the maximum power that can conceivably be produced by the turbine.

An impulse turbine is operating at h = 700 m and  = 150,000 gpm. The Pelton wheel has
a diameter of 20 ft and rotating at 300 rpm. Find the power produced and the
efficiency of the turbine. Cv = 0.94.
