ENGINEERING DESIGN CALCULATION - DENNIS KIRK ENGINEERING Calculation of Gas Properties - GPSA Engineering Data Book - SI Units - 11th Edition 1998 Version 1.510 CALCULATION TITLE Enter details and data into the cells with a yellow background only. Calculated values on the right side are provided for reference only. Uniformly Real Cp, Cv, k and VOS are calculated using the Redlich Kwong EOS. Normalised Data can be stored and recovered from the Library at the right by highlighting mole % mole % and copying the data within the green border and "pasting values" into the library.
