Hey everyone.

1) Is there a calculation to keep my FPM the same through the whole duct system.

If so can you help me out with it?

I seem to keep it the same most of the way with my duct calculator.

But at some point things start to change.

2)
Or is it okay for it to change as long as my FPM dont go less then what my FPM state for that individual run at my desired friction rate?

3) also i heard try and keep my FPM at what my grill will allow?? Not sure if thats correct
