Real Fluid Calculator
Calculate real fluid properties for more than 100 fluids using state-of-the-art Helmholtz equations of state and thermophysical data from the CoolProp library. Real fluids depart from ideal gas behavior as they are compressed. The gold standard in real fluid models is the Helmholtz energy equation of state advanced by NIST and others through publications and the NIST RefProp software. This model uses the CoolProp libary’s implementation.

Helium pressurant tank
- A satellite uses a high-pressure helium pressurant tank Fluid = helium ⏎ to maintain pressure in its fuel tank.
- If the maximum expected operating pressure of the tank is 6000 psi P.psi = 6000 ⏎ at room temperature T.c = 20 ⏎, then what is the helium density? The model infers a density ρ «ctrl+g»r ⏎ of 57 kg/m³ (among many other properties).
