compressibility factor(redirected from Compressibility chart)
compressibility factor[kəm‚pres·ə′bil·əd·ē ‚fak·tər]
The product of the pressure and the volume of a gas, divided by the product of the temperature of the gas and the gas constant; this factor may be inserted in the ideal gas law to take into account the departure of true gases from ideal gas behavior. Also known as deviation factor; gas-deviation factor; supercompressibility factor.
