Chapter 7. Thermodynamics
Compressibility Factor Variation from van der Waals Equation
Concepts Demonstrated
Compressibility factor variation with reduced pressure from the van der Waals equation of state at various reduced temperatures.
Numerical Methods Utilized
Solution of a single nonlinear equation and integration of an ordinary differential equation to permit continuous plotting of various functions.
Problem Statement
The van der Waals equation of state can be used to calculate the compressibility factors for gases, as has been discussed in Problem 2.1. Thermodynamic textbooks often provide charts of compressibility factors for various reduced temperatures, Tr, as a function of reduced pressure, Pr. An example is given by Kyle.[1]
