Steam Tables Pro
This app calculates a comprehensive range of thermodynamic properties for steam using the IAPWS-97 equations. It allows calculations based on various input parameters like pressure, temperature, enthalpy, entropy, and quality, and displays results in charts.
- Calculates properties from pressure and temperature
- Calculates properties from pressure and enthalpy
- Calculates properties from pressure and entropy
- Calculates properties from pressure and quality
- Calculates properties from saturated temperature and quality
- Calculates properties from enthalpy and entropy
- Displays results in T-s, P-h, and H-s charts
- Supports multiple units

Steam Tables calculates the functions below, using the IAPWS-97 equations: •Function(p,t) – to calculate properties from pressure and temperature; •Function(p,h) – to calculate properties from pressure and enthalpy; •Function(p,s) – to calculate properties from pressure and entropy; •Function(Psat,x) – to calculate properties from pressure and quality, for saturated steam and liquid and two fases; •Function(Tsat,x) – to calculate properties from saturated temperature and quality, for saturated steam and liquid and two fases; •Function(h,s) – to calculate properties from entalpy and entropy. From the functions above, you can calculate quickly the properties below: MAIN THERMODYNAMIC PROPERTIES: •Pressure; •Temperature; •Enthalpy; •Entropy; •Vapor Fraction; •Specific Volume; •Internal Energy; •Density; •Region; OTHER THERMODYNAMICA PROPERTIES: •Specific Isobaric Heat Capacity (Cp); •Specific Isochoric Heat Capacity (Cv); •Speed of Sound; •Kappa; •Vapor Volume Fraction. TRANSPORT PROPERTIES: •Dynamic Viscosity; •Kinematic Viscosity; •Prandtl; •Surface Tension; •Thermal Conductivity. MORE •Record the results •See the Records in the Chart T-s, P-h and H-s. •Multiple units. The best thermodynamic properties calculator on the App Store!!!!!

Verdict
The clearest difference is price: Lạc Việt Reader at Free against Steam Tables Pro's $4.99. Lạc Việt Reader also leads on iOS requirement (12.0 vs 15.1). Steam Tables Pro's advantage is review sentiment (26% vs 0%) and update cadence (every 2 months vs every 6 months). On ads, in-app purchases and device support there is nothing between them.
