ABSTRACT
In Chapter 1, we derived a simple equation for the pressure-volume relation of a gas based on elementary considerations. Because many oversimplications were involved in this derivation, it could not be reasonably expected that the result obtained in this manner would even closely approach the behavior of a real gas. Surprisingly, it has been found that the equation can be used to represent the behavior of a large class of actual gases with accuracy usually sufcient for engineering applications. In any case, this equation can be used to predict qualitatively the behavior of most gases, and the results so obtained can be employed as a guide for design or performance purposes.
