Fluid ThermoTables is a fast, accurate thermodynamic property calculator for engineering students and professionals. Calculate all thermodynamic properties of R-134a refrigerant and Steam/Water from any two known state properties, instantly. Stop flipping through tables during exams and homework. Enter what you know, tap Calculate, and get every property of the state point in seconds. FLUIDS SUPPORTED R-134a (HFC-134a refrigerant) — subcooled*, saturation, and superheated regions Steam / Water (H₂O) — subcooled*, saturation, and superheated regions *Subcooled liquid states use saturated liquid properties as an approximation, consistent with standard engineering practice. INPUT PAIRS — enter any two known properties: Temperature & Pressure Temperature & Vapor Quality Pressure & Vapor Quality Pressure & Enthalpy Pressure & Entropy Enthalpy & Entropy Temperature & Enthalpy Temperature & Entropy OUTPUT PROPERTIES Phase region (Saturated Mixture, Subcooled Liquid, Superheated Vapor) Specific volume (v) Density (ρ) Internal energy (u, uf, ug, ufg) Enthalpy (h, hf, hg, hfg) Entropy (s, sf, sg, sfg) Vapor quality (x) Saturation pressure and temperature UNIT SYSTEMS Full SI support: kPa, °C, kJ/kg, kJ/(kg·K), m³/kg Full imperial (I-P) support: psia, °F, Btu/lbm, Btu/(lbm·R), ft³/lbm Independent SI and I-P unit profiles — set your preferred unit for each property separately Switch between SI and I-P instantly with a single tap All property values read directly from standard tables in the active unit system — no conversion errors DESIGNED FOR ENGINEERING STUDENTS Based on the standard property tables used in undergraduate thermodynamics courses Results match published table values to the precision of linear interpolation Property values are obtained by interpolation from standard thermodynamic property tables based on internationally accepted equations of state Perfect for Thermodynamics I and II, HVAC/R coursework, and Rankine/refrigeration cycle analysis
