 I&amp;#39;ve been using Hevacomp Netsys to calculate the ventilation system resistance. However, the results seem a bit high and I don&amp;#39;t know why. The entire system is only within one large room and the results show 119 Pa. Velocities do not exceed 3</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Ventilation high system resistance</title><link>https://communities.bentley.com/thread/681799?ContentTypeID=1</link><pubDate>Thu, 11 Nov 2021 11:24:37 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:48edf891-372c-4c94-a125-a67c2cf30f19</guid><dc:creator>Patrycja Banasiak</dc:creator><description>&lt;p&gt;Hi Shane, I see, thank you for your help, much appreciated.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Ventilation high system resistance</title><link>https://communities.bentley.com/thread/681393?ContentTypeID=1</link><pubDate>Tue, 09 Nov 2021 16:05:51 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:f028c9e1-7c9f-40b0-944f-489104eeca26</guid><dc:creator>Shane Regan</dc:creator><description>&lt;p&gt;Hi Patrycja,&lt;/p&gt;
&lt;p&gt;So the high pressure is predominantly due to section 1:&lt;/p&gt;
&lt;p&gt;&lt;img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/275871/pastedimage1636473833834v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Specifically, the three&amp;nbsp;fittings along section 1&amp;nbsp;that have been added account for the extra pressure&amp;nbsp;- see results with these removed:&lt;/p&gt;
&lt;p&gt;&lt;img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/275871/pastedimage1636473969066v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;I hope this is of assistance.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Ventilation high system resistance</title><link>https://communities.bentley.com/thread/681142?ContentTypeID=1</link><pubDate>Mon, 08 Nov 2021 16:04:08 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:21957985-1e9d-41c2-bc50-815664b7eba5</guid><dc:creator>Patrycja Banasiak</dc:creator><description>&lt;p&gt;Brilliant, thank you.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Ventilation high system resistance</title><link>https://communities.bentley.com/thread/681138?ContentTypeID=1</link><pubDate>Mon, 08 Nov 2021 15:57:08 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:f4e8a803-f45a-4222-8760-895bd25c3983</guid><dc:creator>Shane Regan</dc:creator><description>&lt;p&gt;Hi Patrycja,&lt;/p&gt;
