C.3 Fluid Calculations

C.3.1 Calculations for Steam T & P
When "Steam T & P" is selected in the "Real Gas" selection of the Fluid Menu, the calculations are based on the
equations below.

C.3.1a Density

The density of steam is calculated from the formula given by Keenan and Keys. The given equation is for the volume
of the steam
Where:
tau is 1/ temperature in Kelvin
density = 1/(v/ standard density of water)
