Steam and Natural Gas

[tuitvlugt]

I am struggling on how to handle flow rates for Steam and Natural Gas systems. Pipe connectors allow flow rates in either GPM or Fixture units, but for steam the flow rate is typicaly lbs/hr, and for natural gas the flow rate is typicaly cubic feet per hour (CFH) or BTUH.

Has anyone come up with a good method for dealing with these two systems?

Since I am not doing flow calcs with revit, I just substituted lbs/hr or CFH with GPM and removed the units from the schedules and tags. So, for a 100 CFH boiler, I technically enter 100 GPM, but use a tag and schedule that substitues CFH for GPM.

That is exactly the way we do it and will be the ONLY way you can until Ade$k adds that capability.
Obviously you cannot size the pipe, but you can do the calculations with schedules and create your custom tags.
