Peng Robinson Parameter a, using Peng Robinson Equation given Reduced and Critical Parameters evaluator uses Peng–Robinson Parameter a = ((([R]*(Critical Temperature*Reduced Temperature))/((Reduced Molar Volume*Critical Molar Volume)-Peng–Robinson Parameter b))-(Reduced Pressure*Critical Pressure))*(((Reduced Molar Volume*Critical Molar Volume)^2)+(2*Peng–Robinson Parameter b*(Reduced Molar Volume*Critical Molar Volume))-(Peng–Robinson Parameter b^2))/α-function to evaluate the Peng–Robinson Parameter a, The Peng Robinson Parameter a, using Peng Robinson Equation given Reduced and Critical Parameters formula is defined as an empirical parameter characteristic to equation obtained from Peng–Robinson model of real gas. Peng–Robinson Parameter a is denoted by aPR symbol.
