Is the ratio of the thermodynamic work requirement in the cylinder to actual brake horsepower requirement.

A plot of expected operating characteristics (e.g.., discharge pressure versus inlet capacity, shaft horsepower versus inlet capacity).

The amount of heat in a quantity of matter at a specific temperature and pressure.

The thermal energy used in an industrial process.

A restrictive tube used in a refrigeration system which restricts the flow of freon and allows pressure to build on one side and suction on the other. It is located between the condenser and the evaporator.

Machines in which air or gas is compressed by the mechanical action of rotating vanes or impellers imparting velocity and pressure to the flowing medium. (Raise the pressure of the air by converting the energy from the velocity of the air to pressure.)

The slope (dE/di) at the corrosion potential of a potential (E)/current density (i) curve. Also used to describe the method of measuring corrosion rates using this slope.

For valves and fittings, implies that they are suitable for working pressures between 125 to 175 pounds per square inch.

A discontinuance of electric power supply.

A configuration of an electrical circuit in which the positive lead is connected to the negative lead of another energy producing, conducting, or consuming device. The voltages of each device are additive, whereas the current is not.

A wind moving from the land to the water due to temperature changes in the evening, where the temperature of the land falls below the sea temperature.
