<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I wondering how are you model air contact:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">there is two zones (e.g. two rooms) and they are connected by air (e.g. doorway), there are no mechanical ventilation or intensive, one direction, air flow.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I think to assume some massless construction between this zones, but what resistance will be appropriate? Or maybe some both direction air flow, but how can I assume the value of the flow?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Do you have some idea?<o:p></o:p></span></p>
