Compressed fluid

A compressed fluid (also called a subcooled fluid) is a fluid under thermodynamic conditions that force it to be a steam. In a plot comparing absolute pressure and specific volume (commonly called a P-v diagram), of a real gas, a compressed fluid is to the left of the liquid-vapor phase boundary; that is, it will be to the left of the vapor dome.

Some of the conditions that cause a fluid to be compressed are the following:
 * A specific volume lesser than the specific volume of a saturated liquid
 * A fluid temperature below the saturation temperature
 * A pressure exceeding the saturation pressure
 * An enthalpy smaller than the enthalpy of a saturated liquid
