The Ideal Gas Equation of State

For n moles equation becomes

Density of an Ideal Gas

 Standard Conditions 

1.  Oil and gas occur under a whole range of temperatures and pressures
2. Convenient to express volumes at a reference condition. 
3.  Common practise to relate volumes to surface conditions. 14.7 psia and 60^oF 

Mixtures of Ideal Gases

       Petroleum gases are mixtures of gases - Dalton’s Law and Amagat’s Law 

 

   Dalton’s Law of Partial Pressures

             : Total pressure is the sum of the partial pressures
