Question

The mechanical efficiency of an impulse turbine is

Answer 1

Some energy is wasted to overcome the friction of bearing and other moving parts. Hence keeping this point in mind, the mechanical efficiency is the ratio of actual work available at theturbine to the energy imparted to the wheel.
