Kvo_8 Posted August 20, 2009 Author Report Share Posted August 20, 2009 With pvc, stick with 12-16in^2 per cubic foot. 3.14*r^2 that means about 3 or 4-4" ports? what about the length of each?

iTech Posted August 20, 2009 Report Share Posted August 20, 2009 (edited) Aeros are a bit different. You can use about 8-10in^2/cube. PVC pipe on the other hand still goes by 12-16in^2/cube. And its figured by r*r*3.14...... Where did you get 10 or 11 with 5 cubes? realistically you can squeeze by with about (6) 3" aero ports Well the area of a 3" circle is 4.71 sq. in. So having a minumum of 12 sq in per cube = (5 Cubes * 12) = 60 60/4.71= 12.74 = Which is how many ports you'll need. But I too read somewhere where it stated for aero ports it's less.
