It is commonly assumed that Z at standard conditions (psc = 14.7 psi and T=60F) is equal to 1. Show whether this is a good assumption using the fluid data in Appendix C. Plot the volume versus pressure of 1 lb-mol of this gas from atmospheric pressure to the reservoir pressure, which is equal to 4613 psi. (Use a temperature of 180F.) Comment on the shape of this curve.
