Cobb gives them the "split bellmouth" name but even that's being overly generous. It's just a bellmouth with a useless metal splitter in there. It delays the exhaust gas merge until further down the pipe. bruh please meme

WebFor example, 1-percent rounding of the upstream face corner of the opening perimeter in terms of minimum orifice opening dimension causes about a 3-percent increase of the contraction coefficient. A well-designed bellmouth will eliminate all contraction (Schuster, 1970). Orifices may be partially contracted in two senses. WebA bellmouth consists of several cones of different diameters. The gradient from small to large diameter is worked out by our engineers into efficiently manufactured parts. … WebFeb 19, 2024 · 2:1 sounds like a good initial size ratio as it gives you 4 x the area so on average 1/4 of the velocity. but as said, inlet or out let velocity is up to you depending on your particular circumstances - noise, mixing … bruh please
