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.

Inaccurate
Specific volume in ft3/lb and m3/kg do not match when converting units.
Don’t buy
The app is not usable, it crashes too often.
Instantly Crashes
I would love to use the app but both the Lite and Pro versions instantly crash when opened. iPhone 11. iOS 15.2.1.
Love the esthetic, but it’s wildly inaccurate
I liked the look and feel of this App, particularly the ability to see stored points on the curve. However, I started to notice that sometimes my results wouldn’t match my plant parameters. It all came to a head when a particular calculation yielded a result roughly off by a factor of 255x. P=2200 psia, T=551 F yielded 11944 lbm/ft3 when the result should be ~ 46.7 lbm/ft3. Nothing is worse than being technically wrong. Deleting the App even though I paid money for it because being this wrong once can’t be trusted for anything.
