Pneumatic motor several factors which include the amount of air pressure at the motor inlet and the diameter of the housing. One application for vane-type air motors is to start large industrial diesel or natural gas engines. Stored energy in the form of compressed air, nitrogen or natural gas enters the sealed motor chamber and exerts pressure against the vanes of a rotor. This causes the rotor to turn at high speed. Because the engine flywheel requires a great deal of torque to start the engine, reduction gears are used. Reduction gears create high torque levels with the lower amounts of energy
Losses in steam turbines Losses in steam turbines Any turbomachine extracts energy from high-pressure steam and converts it into shaft work. The total energy content available in steam supplied to the steam turbine is not completely recovered in the form of mechanical energy. There are certain losses in energy of steam which occur inside a turbine... In practice the flow of steam through nozzle is not isentropic, but accompanied with losses which decrease the kinetic energy of steam coming out of the nozzle. The decrease in kinetic energy is due to the following reasons Steam leaves the boiler and reaches the condenser after passing
