What happens if ... (port questions) (1 Viewer)

[Neil Joseph]

What is the effect of having ports of different lengths and/or diameters in the same box?
Also, with a 90 degree elbow in a port, do you use the average length through the elbow to use in the total port length. In other words, going through the short side of the elbow is a few inches less than going through the long side of the elbow.
Sorry for the silly questions and thanks in advance.

On the 90 degree elbow, just measure the center line distance, that should be good enough for the added length from the elbow. Or average the lengths of the outer inside, and the inner inside. Both should be close approximations.
Have no idea on the non-equal length/width ports though. Suffice it to say, probably not a good idea.
