.IBPSA.Utilities.Psychrometrics.pW_X

Information

Block to compute the water vapor partial pressure for a given humidity ratio.

If use_p_in is false (default option), the p parameter is used as atmospheric pressure, and the p_in input connector is disabled; if use_p_in is true, then the p parameter is ignored, and the value provided by the input connector is used instead.

Revisions

• October 3, 2014, by Michael Wetter:
  Changed assignment of nominal value to avoid in OpenModelica the warning alias set with different nominal values.
• February 17, 2010 by Michael Wetter:
  Renamed block from VaporPressure_X to pW_X.
• April 14, 2009 by Michael Wetter:
  Converted model to block because RealInput are obsolete in Modelica 3.0.
• August 7, 2008 by Michael Wetter:
  First implementation.
