![]() Note that the Excel program uses SI units for the thermodynamic property values. The program is compatible with all versions of Excel.Ĭlick on this link to see a screen capture of the Excel spreadsheet for the superheated region. We can calculate the work by determining the area enclosed by the cycle on the p-V diagram. ![]() It was born in the 19th century as scientists were first discovering how to build and operate steam engines. ![]() To use the calculator you need to have Microsoft Excel installed on your computer. Thermodynamics is a branch of physics which deals with the energy and work of a system. You need to uncompress this file before you can access the calculator. In the subcooled and superheated region, you can specify ( P, T), ( P, v), ( P, u), ( P, h), or ( P, s), and automatically solve for the remaining thermodynamic properties.Īll the files that come with this calculator are contained in a single (compressed) file, in the "zip" format. In the saturated region, you can specify any of the six thermodynamic properties and automatically solve for the remaining five. Note: - You cannot use commas (,) as decimal points. Set your preferences for these steam tables. Should saturated steam be heated at constant pressure, its temperature will rise, producing superheated steam. This interpolator will plot a point of interpolation on a line. The superheated steam region depicts steam at a temperature higher than its saturation temperature. It calculates thermodynamic properties in the subcooled region for an absolute pressure range of 5-50 MPa, using 7 data tables spread apart over this range. The online interpolation calculator will provide you the following results: A new interpolated value will be displayed at that point where we want to conduct interpolating. The Excel spreadsheet calculates thermodynamic properties in the superheated region for an absolute pressure range of 0.01-80 MPa, using 30 data tables spread apart over this pressure range. ![]() The calculator uses data points from thermodynamic property tables, and uses linear interpolation to calculate the following six thermodynamic properties: Temperature ( T), pressure ( P), specific volume ( v), energy ( u), enthalpy ( h), and entropy ( s). This calculator is programmed in Microsoft Excel. I created a steam table calculator which makes it easy to calculate the thermodynamic properties of water in the subcooled, saturated, and superheated region. ![]()
