Alrighty, I have tried and tried, but cant seem to get this to a point to which i can program this into a program (im still a little rusty)
Code:
Fb = .159sqrt((Av(1.84x10^8))/(Vb(Lv+.823sqrt(Av))))
Fb = Tuning Frequency (Frequency of box)
Av = Area of Vent (In sq inches)
Vb = Volume of box (in cu inches)
Lv = Length of Vent (Port)(What i want to be alone, so i can just plug it in....)
Any help is much appreciated |

Input "Area of vent? ",A
Input "Volume of box? ",B
Input "Length of vent? ",C
Disp .159sqrt((A(1.84x10^8))/(B(C+.823sqrt(A))))
I'm not quite sure what your asking... but I think this is what you want... not quite sure.

code boxes! code boxes! code boxes!.... I think i may have gotten it on irc, please check:
Code:
A*(1.84E8)/(V(F/.159)^2)-.823sqrt(A)

You can uncheck the "Enable Smilies" check box if you want.
Pseudoprogrammer has the right formula for your purposes. You might want to edit that post...
Code:
A(1.84E8)/(V(F/.159)^2)-.823sqrt(A)
You can take out the multiplication symbol after the A

You could also use: 4651704A/F²/V-.823√(A
Out of curiosity, where did .159, 1.84x10^8, and .823 come from?
I think .159 might be 1/(2[font="times new roman"]π), but that's only a hunch.
[EDIT]
I found a good link here.
