Note

The SteamTab Duo demo is limited in temperature and pressure for both the Scientific (IAPWS-95) and the industrial (IAPWS-IF97) formulations. The temperature and pressure limitations of this demonstration package are:

150 ºC  <= Temperature <= 200 ºC, and
  5 bar <= Pressure    <=  10 bar

If you specify a temperature or pressure range that is outside the demo range, SteamTab Duo will return the #VALUE! error in Excel versions or the ERR error in Lotus versions. Also, the SteamTab Duo demonstration package contains only the compressor template that illustrates a steam compressor design.
