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.

Absolutely!!! After the next upgrade to Pro, it doesn't even open, but the Easy One works... Pro used to work before.… It's an outrage!!! ### 2/5 — Se cierra la aplicación *2024-06-27, version 5.0.3* Sigue cerrándose la aplicación, es muy molesto así, para ser una aplicación por la cual tienes que pagar deberían optimizarla mejor ### 5/5 — Mai avuto un problema *2024-05-28, version 5.0.3* Necessitavo di comprarla per studiare e passare un esame. Mai avuto problema di nessun genere. ### 2/5 — Inaccurate *2024-02-12* Specific volume in ft3/lb and m3/kg do not match when converting units. ### 5/5 — Erro *2023-09-26* Tento abrir o aplicativo e ele fecha imediatamente, IOS 17.0.1 ### 1/5 — Si chiude e non funziona più *2023-03-28, version 5.0.1* Per favore risolvete. ### 1/5 — Don’t buy *2023-03-06* The app is not usable, it crashes too often. ### 1/5 — NOT WORKING APPS, VERY BAD SERVICE, DON’T PAY FOR IT GUYS IT IS WORTHLESS !!! *2023-02-08, version 5.0.1* Every time use this app it keeps closing without any reason which us very frustrating, so I’ll suggest people not to buy this apps as it is not worth it to pay for it and not getting a simple calculation ### 1/5 — Too many issues *2022-10-05, version 4.1.4* I paid for this to hopefully get some good functionality but it has many problems. First of all it installs with a point already calculated which appears on the graphs, but cannot be deleted. The graph axes do not use the same units one selects. Also, p-h chart starts at 1 MPa instead of something much less like 0.01 MPa. Scale for T-s no better. For recorded data calculated you can disable some properties but the data heading is still displayed. There are many more but that’s enough to warrant poor review and makes it not worth using. ### 1/5 — Не рекомендую *2022-02-22, version 4.1.4* Ужас, постоянно вылетает, не работает. Не тратьте деньги пацаны ## Frequently asked questions about Steam Tables Pro ### What thermodynamic properties can Steam Tables Pro calculate?
