Critical Pressure in Volumetric Properties of Pure Fluids Formulas

Critical Pressure is the minimum pressure required to liquify a substance at the critical temperature. And is denoted by P_c. Critical Pressure is usually measured using the Pascal for Pressure. Note that the value of Critical Pressure is always positive. Typically, the value of Critical Pressure is greater than 0.
