What is a air compressor used for?

An air compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. 

This increased pressure forces the air out of the compressed air to generate electrical energy. A compressor motor turns an air compressor (often with an induction motor, an electric motor, or both). 

The work done in turning the compressor motor is usually to provide more air for use. When using an induction motor, the airflow is less than when using an electric motor. When using a diesel engine, there is more work done to provide more air for use.

 I won't go into all the particulars of the different types, but the key is to think of it as a closed loop.

The major energy products in the compressed air (in the presence of the adsorption of CO 2 and H 2 O) include heat (heat is the fractional conversion of CO 2 to water vapor) and work (electric power). These are products of the conversion of CO 2 and H 2 O into less dense forms of energy (air molecules). 

The heat is proportional to the ratio of the compressibility of the air to the density of the air (mole

Thrust

The thrust of a motor is usually measured in pounds per square inch (lbs/in²) or units of revolutions per minute. Thrust is a measure of how fast the exhaust gas exhausts out of the exhaust pipe. The higher the thrust, the faster the exhaust gas exits. Thrust is measured in constant pounds. Thrust equals the power x the square of the velocity x the square of the time. Thrust is usually represented in other units, such as ft-lb or hp.
