<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">We are trying to compute the wet bulb temperature of an air. We know the enthalpy and the relative humidity of this air.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">There is a type 33 which seems able to do this : it is labeled “Physical Phenomena\ Thermodynamic Properties \ Psychrometrics \ Enthalpy and relative humidity
known”. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Tahoma","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">So we take this “type33h” but the only inputs available are enthalpy and humidity ratio, instead of relative humidity. This seems quite odd since this is what
the “humidity ratio and enthalpy known” type 33 is supposed to do.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">Has anyone encountered this kind of problem ?<o:p></o:p></span></p>
