I haven&#39;t used it for several years and lost some knowledge and looking for some assistance.</p> <p>I have modeled a CWS system in Netsys, inserted a system marker which doesn&#39;t return any issues. The problem occurs when I am looking to get the system flow rate and pressure drop. When i sized the system I need to insert a water tank height or system pressure and this point, which I do but I had assumed a total system flow rate and required pressure drop would still be calculated, and it allow a pump selection.</p> <p>Am i missing something? I am trying to model the boosted cold water system, so the pressure and flow rate are a result I would assume Netsys would return.</p> <p>Anyone&#39;s assistance would be appreciated.</p> <p>Neil</p><div style="clear:both;"></div>
