Fluid Properties

Select a fluid, enter the state point, and calculate the engineering properties.

State point
Thermo records can be calculated as gas/vapor, liquid, solid, or backend equilibrium where data is available.
%
State mode
T-P is the standard property pack. Saturation and P-h modes require fluids supported by the reference backend.
0 liquid, 1 vapor
Flow and heat transfer Re, Pe, Nu, Gr, Ra
Optional sizing inputs add Reynolds, Peclet, Nusselt, Grashof, and Rayleigh numbers to the same property result.
Flow velocity for Reynolds and Peclet numbers.
Characteristic length, diameter, hydraulic diameter, or plate length.
Heat-transfer coefficient for Nusselt number.
Temperature difference for buoyancy numbers.
Blank uses 1/T for gases.
Property engine Auto recommended
Auto uses the approved backend or local model for the selected fluid.
