Abstract
An equation of state for medium high-temperature conditions has been developed based upon an abel-type covolume model. The formation of discrete clusters was examined using statistical thermodynamics but was found to be unimportant to the equation of state for most conditions considered here. Theoretical pv isotherms using this simple model agreed to within several percent with experimental pv isotherms for ar, n2, and co2 for densities between 0.001 and 1.5 G/cm3 for temperatures about 100 k greater than the critical temperature. For these conditions the ideal gas, van der waals, and beattie-bridgman models agreed only to within about 25 percent. Agreement for h2o was less satisfactory and comparable with that obtained with the other models.
