What's new in version 5.6

  1. The software package "WaterSteamPro" recommended by Department of General Inspection for Exploitation of Electrical Power Stations and Networks of Russian Joint Stock Company Unified Energy System of Russia (RAO "UES of Russia" - http://www.rao-ees.ru/en/) for usage in energetics (information letter # IP-14-27-2001 from 03.08.2001).
  2. Significantly improved the speed of calculation. Approximate calcultation speed increasing given here.
  3. Added 8 new functions for complexing properties calculation. It's significally decrease the time of calculation when you need more then one property at one point. In addtition, new functions allow to calculate pressure and temperature derivates of main properties. List of new functions given here.
  4. Added new function wspDPDTST for calculating derivative of saturation pressure on saturation temperature.
  5. Signfically revision of calculating properties in double-phase region:
  6. Added 2 new functions for calculating isochoric heat capacity (Cv) at saturation line from the double-phase region area. These functions allow rightly calculate (from the point of view of thermodynamic) next propeties in double-phase area: isochoric heat capacity, isoentropic exponent, sound velocity. List of new functions given here.
  7. Function wspCVSTX now used functions, mentioned above, which consider isochoric heat capacity jump at saturation line. It's allow to remove this function from "non thermodynamic" category.
  8. Function wspKSTX now used functions, mentioned above, which consider isochoric heat capacity jump at saturation line. It's allow to remove this function from "non thermodynamic" category.
  9. Function wspWSTX now used functions, mentioned above, which consider isochoric heat capacity jump at saturation line. It's allow to remove this function from "non thermodynamic" category.
  10. Function for calculating Joule-Thompson coefficient in double-phase area (wspJOULETHOMPSONSTX) now calculate the value, proper from the point of view of thermodynamic: JT = (dt/dp)h=const, but not from degree of dryness (as in previous versions). It's allow to remove this function from "non thermodynamic" category.
  11. Search is added in documentation .
