I am about to design a box 2 15'' RE HCs and would like to get to 8 cubes, 30hz, after displacements using two full length 6'' PSP AeroPorts but I am having trouble calculating displacement.
Anyone ever run a calc for this or have any guidance?
Help will be very much appreciated.
Thanks,
Kevin

I believe he's asking for the volume of displace of the actual port.

That isn't exact displacement. You have to take the integral of the curve and rotate it around the z axis to get the precise displacement.r2 x pi x length / 1728 = cf
I have the exact number but I misplace it somewhere. It's been 3 years since I've designed something with it.

Yea, the displacement of the aero as if it were a normal, round port would be close enough because it'd be such a small amount off on airspace if you really wanted to factor in the flared portion

You gotta know how to do this if you design boxes.
