How do you measure......?

How would I determine how many square inches of port I have if I'm using a round port? For example, a 4" port that is 13.15 inches long.......

But, you need a considerably less amount of space when using a round port as apposed to a square port.

Area and volume are seperate..

this is true.....If I need about 32 square inches of port and I have a port that is 4"x13.15" long, how many square inches is the port? Pi x radius^2 would give me 12.56 correct?

yes a 4" port is 12.56^2 of port area. Generally if using aero ports you can get by with about 1/2 of the port area of a normal slot port...

Why is this?

Oh I see, so in this case I still need a little more port correct?

wouldnt it be (pi)(r^2)(height) when looking for volume at least? so 12.56x13.5=168.75...???
