I want to use the built in pressure loss calcs for a slurry mixture, but can only choose from the original list of types. I need the dynamic viscosity and density to be different values, but they aren't editable.</P><P>&nbsp;</P><P>Any help is greatly appreciated.&nbsp;</P><P>&nbsp;</P> Wed, 09 Jul 2025 15:37:56 GMT https://forums.autodesk.com/t5/revit-mep-forum/creating-a-new-fluid-type-for-piping-systems/m-p/13717923#M84130 quinn_leschuk 2025-07-09T15:37:56Z https://forums.autodesk.com/t5/revit-mep-forum/creating-a-new-fluid-type-for-piping-systems/m-p/13719410#M84140 <P>You need to delete temperatures and add new one (or add the same ones back again) and you can edit values for each temperature.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="iainsavage_0-1752152209468.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1551150i7E2F26081063438A/image-size/medium?v=v2&amp;px=400" role="button" title="iainsavage_0-1752152209468.png" alt="iainsavage_0-1752152209468.png" /></span></P><P>&nbsp;</P> Thu, 10 Jul 2025 12:57:04 GMT https://forums.autodesk.com/t5/revit-mep-forum/creating-a-new-fluid-type-for-piping-systems/m-p/13719410#M84140 iainsavage 2025-07-10T12:57:04Z
