That’s a nice set up.

I was wondering if there was some increased efficiency, not just at the bottom of the hood, but in terms of capture and flow across the whole hood and above the 4’x10’ slot or 5” hole. They spend a lot of time engineering transitions from one size duct to another and from round to rectangular duct. I understand these efforts in terms of reducing CFM killing turbulence. Maybe the long slot would be more effective as a transition into the 5” round duct if it was a proper engineered transition like a floor register boot. There must be some reason they go to that trouble instead of just using round pipe into the rooms of a house. Likely overthinking this, but I find it interesting and it’s not expensive to implement.
