Thermodynamics Processes and Equilibrium Quiz

P (Pa) = Absolute pressure of the gas T (K) = Absolute temperature of the gas v (m3/kg) = Specific volume of the gas R (J/kg.K) = The gas constant

Z = 1 for ideal gases = Compressibility factor is unity for ideal gases Z can be greater or less than unity for real gases = Compressibility factor varies for real gases Z is determined from compressibility factor chart at Pr and Tr = Z values are obtained from a chart at reduced pressure and temperature f(gas, Pr, Tr) = Function to calculate Z based on gas type, reduced pressure, and temperature

Z = Vreal / Videal = Definition of compressibility factor Z Z = f(gas, Pr, Tr) = Expression to calculate Z based on gas type, reduced pressure, and temperature Z = 1 - 2a/v + b/v^2 = Van der Waals equation for compressibility factor Z Z = Pv/RT = Ideal gas law rearranged for compressibility factor Z
