Determine the maximum efficiency, Mechanical Engineering

Assignment Help:

A jet strikes tangentially a smooth curved vane moving in the similar direction as the jet, and the jet gets reversed in the direction. Prove that the maximum efficiency is slightly less than 60 percent. The following data relate to a Pelton wheel:

Head = 72 m,

speed of wheel = 240 r.p.m.,

speed , ratio = 0.45,

coefficient of velocity = 0.98,

shaft power of the wheel = 115 kW,

overall efficiency = 85%,

Design the Pelton wheel.
