The losses in efficiency for a practical wind turbine are caused by the viscous drag on the blades, the swirl imparted to the air flow by the rotor, and the power losses in the transmission and electrical system.

pump efficiency only. Operators may want their pumping unit efficiency to be evaluated for the complete unit. If so, the efficiency of the motor or engine will be included, and the overall efficiency will be lower than pump efficiency. WHP = HQ 3960 Where H is the total head of the water in feet and Q is the flow rate in gallons per minute.

The Pelton wheel is an impulse-type water turbine. It was invented by Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel .

There are two types of steam turbine impulse turbine and reaction turbine. Both types of steam turbines have different efficiency due to their different working principles but the efficiency of both types of steam turbines is expressed by the following equation.

The efficiency of any turbine or engine can be defined as its ability to convert the input energy into useful output energy which is expressed in the form of the following equation.. Efficiency (ɳ) = Output / Input. An ideal turbine with efficiency is the one which converts all its input energy into output work without dissipating energy in the form of heat or any other form.
