UNITS:This application is written around the calculations in the SI Units version of the Data Books and all calculations are carried out in SI units.The application, however, continually provides the outcome in both SI and US units on the two worksheets.The controls on the US units worksheet allow the operator to select which units they want to use to enter the data for the calculations.This also resets the base pressure and temperature for the calculations to either MSC (0 kPa(g) and 15 oC) or STP (0 psi(g) and 60oC) to suit. If NTP is required as the base the user can manually change the settings.

Enter details and data into the cells with a yellow background only.Calculated values on the right side are provided for reference only.

Real Cp, Cv, k and VOS are calculated using the Redlich Kwong EOS.Data can be stored and recovered from the Library at the right by highlighting

and copying the data within the green border and "pasting values" into the library.
