Gas streams are often cooled either by expansion through a throttling valve or in a turbine. to measure the relative efficiency of these two processes, the term Kh/Ks is often coated. The throttling coefficient is defined as Vh = whereas the isentropic coefficient is Ks =
Calculate for CO2 at 319.4K over a range of reduced pressures from 0.1 to 2. What conclusions can you draw? Also, determine the compressibility factor over the same pressure range at 319.4 K. Use the peng-robinson equation of state in your calculations. For CO2 , T-C=304.2K, Pc=73.76 bar .
