Thermodynamics Calculator vs Steam Tables Pro

Thermodynamics Calculator puts 44 thermodynamics and heat-transfer calculators — plus a library of thermal engineering reference tables — in one fast, offline app for engineers and students. Sizing a heat exchanger, checking a Carnot efficiency, or looking up the emissivity of a material? You get the formula, the result, and the reference data in seconds. WHY ENGINEERS USE IT • Solve for any variable — on most calculators, rearrange the formula and solve for whichever value you're missing, not just the "standard" output. • SI and USCS (Imperial) units — switch the whole app between metric and imperial with one tap; every input, result, and unit label updates instantly. • Reference tables built in — emissivity coefficients, thermal conductivity of common liquids and heat-exchanger materials, radiation constants, and more. • Find it fast — search plus category filters: Heat Transfer, Thermal Expansion, Radiation, Energy & Work, Dimensionless Numbers, Properties & Tables. WHO IT'S FOR Mechanical, chemical, and HVAC engineers, and thermodynamics / heat-transfer students who want quick, reliable answers without digging through a textbook.

Calculate water and steam properties with the IAPWS-IF97 equations. Choose six input combinations: pressure and temperature (p·T), pressure and enthalpy (p·h), pressure and entropy (p·s), pressure and quality (p·x), temperature and quality (T·x), or enthalpy and entropy (h·s). Find absolute pressure, temperature, enthalpy, entropy, vapor quality, specific volume, internal energy, density, and thermodynamic region. Explore heat capacities, speed of sound, the Cp/Cv ratio, vapor volume fraction, and transport properties. Save states to compare results and plot points on T–s, p–h, and h–s diagrams. Choose the units you use in study or work. Pressure units explicitly indicate absolute pressure, such as bar(a). Learn inside the app with a usage guide, essential concepts, explanations of each property, and worked examples for boilers, turbines, and valves. Explore boiler superheating, turbine isentropic efficiency, and constant enthalpy during throttling, with T–s and p–h diagrams. The calculator, guide, and tutorial are available offline in English and Portuguese.
