I am using Netsys to design the cold water system for an industrial site. When I run the calculation it does not achieve the sum of the outlets. I&#39;ve narrowed this down to two places where the components when added mathematically are greater than the flow rate produced by Netsys. The screenshot below is one of the problem areas. I would have expected the flow rate on the left to be:-</p> <p>8.151 + 0.269 = 8.42 l/s</p> <p>(Netsys figure is 8.19)</p> <p></p> <p><img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/275871/pastedimage1563200530106v1.png" alt=" " /></p> <p>Thanks</p> <p>Stewart Bullock</p><div style="clear:both;"></div>https://communities.bentley.com/products/building/performance/f/hevacomp-forum/142952/netsys-hws-pipe-sizingWed, 08 Nov 2017 12:12:41 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ca81f67a-e2b5-4f01-a6f5-57b6cba912f1Stewart Bulllock<p>Good afternoon</p> <p>I am using Netsys for a simple HWS project. When I size the system I am getting an excessive pressure drop to an outlet (683n/m2). The outlet details are as follows:</p> <p>Loading unit = 1</p> <p>Max flow rate = 0.05 l/s</p> <p>If you require more details of my system please do not hesitate to contact me.</p> <p>Regards</p> <p>Stewart</p><div style="clear:both;"></div>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Wed, 08 Nov 2017 01:23:32 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:2fbe7754-c9ab-4546-8557-7fac1c0cad90Ask a question in a forum.
