PL= Port length (inches)

x[1.84 * 10^8] ____

_______________ - .823 * \/ x

PL = y[z\.159^2]

and remember...

do all math on TOP

do all math on BOTTOM

divide TOP by BOTTOM

SUBTRACT .823*square root of X

that is port length.

.

using this. i got a port length of 22368.8 in. that obviously wont work. where did i go wrong. my x=52, y=3276 cubes, z=33hz..... please help the slow //content.invisioncic.com/y282845/emoticons/help.gif.cee8f684da1ba626487a8bc51152e1ec.gif i'm not asking for money, just answers. thank you
