Is the ratio of the polytropic compression energy transferred to the gas to the actual energy transferred to the gas.

Is the ratio of actual capacity to piston displacement, stated as a percentage.

A compressor belonging to the group of dynamic compressors.

A change in dimensions directly proportional to and in phase with an increase or decrease in applied force.

The maximum stress that a material is capable of sustaining without any permanent strain (deformation) remaining upon complete release of the stress.

The property of a material by virtue of which deformation caused by stress disappears upon removal of the stress. A perfectly elastic body completely recovers its original shape and dimensions after release of stress.

The ratio of the percentage change in the quantity of a good or service demanded to the percentage change in the price.

A natural or synthetic polymer, which at room temperature can be stretched repeatedly to at least twice its original length, and which after removal of the tensile load will immediately and forcibly return to approximately its original length.

Electric.

A condition that results from an imbalance between the number of protons and the number of electrons in a substance.

The path followed by electrons from a generation source, through an electrical system, and returning to the source.

See conductivity.

The amount of work accomplished by electrical power, usually measured in kilowatt-hours (kWh). One kWh is 1,000 Watts and is equal to 3,413 Btu.2.The energy of moving electrons.

An air heater in which air is blown over electric resistance heating coils.

A hygrometer which uses a transducing element whose electrical properties are a function of atmospheric water vapor content. The humidity strip and carbon-film hygrometer element are examples of such a transducer.
