Heat Capacity Ratios Calculated From The Benedict-Webb-Rubin Equation State, Edward George Delaney
Heat Capacity Ratios Calculated From The Benedict-Webb-Rubin Equation State, Edward George Delaney
Theses
The ratio of the isobaric heat capacity to the constant volume heat capacity has been calculated over a range of temperatures and pressures for the following hydrocarbons: methane, ethylene, ethane, propane, and n-butane. Graphs and tables of calculated data are presented showing the effect of temperature and pressure on the ratio of the heat capacities for these compounds.
The deviations of the heat capacities from ideal gas behavior were calculated by previous investigators from an equation based on the Benedict-Webb-Rubin equation of state, Experimental data were used to evaluate the heat capacities of the ideal gases, and were used together …
A Generalized Correlation For The Effect Of Pressure On The Isobaric Heat Capacity Of Gases, Alvin Harvey Weiss
A Generalized Correlation For The Effect Of Pressure On The Isobaric Heat Capacity Of Gases, Alvin Harvey Weiss
Theses
A generalized correlation is submitted for the deviation of the isobaric heat capacity of hydrocarbons from the ideal state. The range of conditions included is from reduced pressure = 0.2 - 15 and reduced temperature = 1.0 - 5.5. The curves presented have been based on data calculated from the Benedict - Webb - Rubin Equation of State, which is believed to be the most accurate method presently available for caleulating the heat capacity deviation.
The results indicate that the order of magnitude of the correction ts quite large, especially in the critical region. The average absolute error of this …
