An impulse turbine operating at a net head of 2000 ft uses a Pelton wheel of diameter 12 ft and a jet flow area of 5 in. Find the turbine power corresponding to the best efficiency. Use velocity coefficient of 0.94 and a bucket angle of 165^o.

Use the Bernoulli equation and show that, for a wind turbine, the wind velocity is the arithmetic average of the velocity upstream and downstream of the propeller.
