Abstract
The effect of pressure and temperature on the isobaric heat capacity at constant volume for ethylene relative to the ideal gas state is presented. The results cover pressures from 0 to 10,000 FA and temperatures from 32.0°F to 2372.0°F.
The deviation of the isobaric heat capacity of ethylene from the ideal gas state for the wide range of pressure and temperature covered was found from an equation derived from the Benedict-Webb-Rubin equation of state. Graphs and tables relating the deviation of the isobaric h capacity: the deviation of heat capacity at constant volume, pressures and temperature are included.
The results show that the deviation of the isobaric heat capacity from the ideal gas state caused by the effect of pressure must not be neglected. The correction is large enough to introduce considerable error in thermal calculations if it is not applied. The greatest error would occur near the critical point if the effect of pressure were neglected.
A comparison of the calculated data with those of previous investigators has been made and is included in the discussion.
