Pneumatic motor Pneumatic motor A pneumatic motor (air motor) or compressed air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is supplied by either a vane type air motor, piston air motor, air turbine or gear type motor. Pneumatic motors have existed in many forms over the past two centuries, ranging in size from hand-held motors to engines of up to several hundred horsepower. Some
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
