Working with m3/h instead of l/s

[goyete]

Hello, I'm introducing in drawing and calculating ducts with MEP and I don't know if it's possible to works by deffect with m3/h instead l/s. Is it possible? Where can I change it?

Another question of personalizing MEP. The round duct MVpart has several diameters, for example 125 mm and 150 mm. If I want to add a new diameter, I have gone to Manage, Catalog Editor and have edited the round duct and insert a cell with the 135 mm, for example. I reload MEP and if I introduce a new round duct, in the list MEP doesn't show this new diameter but MEP has this diameter internally becouse if I manually introduce the 135 mm, he doesn't advise me for creating a custom size part. Any suggestion?

Thanks!

Sorry, I found it the solution for the first question: Drawing Setup, HVAC and there, define units for flow.
