Water and Steam Properties, known as WASP, is a Windows 95 application. For years the DOS version of this program was one of the most frequently downloaded steam tables programs on the Internet. The Windows 95 version retains all the power of the original, with the added ease of use and flexibility afforded by the Windows interface.

You can download the evaluation version (420 kb). This version is fully functional, but has a time limit per session. To install, unzip the download file into a temporary directory and run Wasp_Setup.exe

This program is aimed at mechanical and chemical engineers. It calculates the physical properties of ice, water and steam in many popular units. It contains data for 15 fixed and 17 variable properties from -100 to 800 deg C and up to 1000 bar.

It replaces printed Steam Tables but covers many more properties and eliminates the need to interpolate between data points. WASP has context sensitive on-line Help. The calculated data points match published data very closely. This program can be used to calculate physical properties for known temperature and pressure conditions, or it can search for the conditions that give rise to particular values of properties.
