About StateCalc
THERMODYNAMIC PROPERTIES CALCULATOR FOR 88 MATERIALS
Calculate thermodynamic properties of different industrial important materials based on the CoolProp thermophysical properties database for pure and pseudo-pure fluids.
1 - Find all the thermodynamic properties for Steam, Ammonia, Propane, R-22, R-134a, Carbon Dioxide, Carbon Monoxide, Carbonyl Sulfide, Hydrogen Sulfide, Oxygen, and 78 other materials available for in-app purchase.
2 - See the location of the fixed state on T - s, T - v, and P - h diagrams.
3 - Available properties are temperature, pressure, specific volume, internal energy, enthalpy, entropy, quality, specific heat capacities, sound speed, thermal conductivity, and viscosity.
4 - Compressed liquid, saturated, and super-heated regions are automatically identified.
5 - Two sets of predefined unit systems (SI and British) plus custom units defined separately for each variable.
6 - Information sheet for each pure fluid indicating the chemical and skeletal formula, GHS hazard specification, critical and triple point information, CAS number, and molar mass.
7 - 4 reference states of default, IIR, ASHRAE, and NBP.
8 - Ability to email or text message the calculated properties.
