How fast do you think you can go before it causes problems for being too fast?
Reason is I have two boxes designed. One has a port velocity just about 48 m/s the other design has a velocity up neat 70 some odd m/s.
Question is how fast can you go before the port becomes inefficient?
The way I understand it is that the port velocity adds some major oomph to the pressurization of the cabin the faster it is. The problem is though that the air can only move so fast before it starts tumbling over itself. In other words, the aerodynamics of the port walls will slow the air flow down and you get uneven pressure. I know there is a point where you hit that but I don't remember what that point is.
