Engineering Steam Tables calculates the thermodynamic properties of saturated and superheated steam. It uses the inch-pound English system of units (ºF, psia, cu.ft./lbm. BTU/lbm, BTU/lbm/R, lb*s/sq.ft., ft/s, lbm/cu.ft.) as default, but the user may select SI units if desired.

Given two properties, Engineering Steam Tables will determine the value for the following water/steam properties: temperature, pressure, steam quality, enthalpy, entropy, saturation temperature, saturation pressure, degrees of superheat, degrees of subcooling, dynamic viscosity, critical velocity, density, and specific gravity.

The results of the calculation can be sent via e-mail (as text or attached CSV file) or text messaging (sms).
