port conversion

dranreb&* · 21st August 2004, 07:13 PM

just a newbie question. How you convert a square port to a
circular port is it the volume or there is another way.

Keep the cross-sectional area the same for the same length.

I'm quite confused

example I do have 7wx2hx6L square port to convert to circular, how it supposed to be.

Keep the length at 6.
Area of your port is 7*2=14
Area of a circle is Pi*(r squared)
So r = sqrt(14/Pi) =2.1
