600

The fastest air speed in any pneumatic system should be no more than ____________ fps.

zero

Absolute ____________ is the hypothetical temperature at which molecular motion ceases, precisely -273.15°C (-459.67°F).

Receiver

A(n) ____________ is a specialized vessel that provides storage of gas for use in a pneumatic system.

Charle's

____________ law states that when the pressure of a gas is constant, the volume of the gas has a direct relationship with its absolute temperature.

Gay Lussac's

____________ law that states that when the volume of a gas is held constant, the pressure exerted by the gas has a direct relationship to its absolute temperature.

Standard Cubic Feet Per Minute

Air compressors in pneumatic systems are rated in ____________.

Air Flow

____________ is the movement of air in a pneumatic system through pipes, tubing, and hoses that transmit energy produced by the air compressor to the location where it is needed to accomplish work.

Standard Cubic Feet Per minute

____________ is a unit of measure that assumes a constant atmospheric environment for air before it is pushed into a system.

pneumatic
