## What is Steam Props?

This app will be picked out from a large group of competitors because of its excellent accuracy, inclusion of all feasible input parameters and the ability to produce results for 3 different cases simultaneously.  So, you can enter the parameters, which can be of the same type or different types, for 3 different conditions and compare the results with each other at the same time. 
The latest version of Steam Tables published by ASME has been used for predicting the thermodynamic properties of steam and water. Therefore, the range of data validity with this app is the same as with ASME Steam Tables, i.e. pressure ranging from 0.0006117 MPa to 22.064 MPa for the case of saturated steam, and pressure ranging from 0.005 MPa to 100 MPa and temperature ranging from 33°C to 800°C for the case of superheated steam. 
Excellent accuracies of ±0.08% and ±0.34% are established for the results calculated for saturated and superheated steam, respectively. This app also supports a large variety of units in addition to the SI (metric) units and U.S. Customary Units.
The following thermodynamic properties are covered for the saturated steam case:
Temperature, Pressure, Vapor Volume, Vapor Density, Vapor Internal Energy, Vapor Enthalpy, Vapor Entropy, Liquid Volume, Liquid Density, Liquid Internal Energy, Liquid Enthalpy, and Liquid Entropy. Given values for any of these properties, the app can calculate all the other properties. For the case of superheated steam, any binary combination of the thermodynamic properties out of 19 different possible combinations (presented below) can be specified to calculate all the corresponding properties:
Temperature-Pressure, Temperature-Volume, Temperature-Density, Temperature-Internal Energy, Temperature-Enthalpy, Temperature-Entropy, Pressure-Volume, Pressure-Density, Pressure-Internal Energy, Pressure-Enthalpy, Pressure-Entropy, Volume-Internal Energy, Volume-Enthalpy, Volume-Entropy, Density-Internal Energy, Density-Enthalpy, Density-Entropy, Internal Energy -Entropy, and Enthalpy-Entropy.
