Z = N^{0.5} \cdot d \sqrt{T [1 + f (A) (\frac{D^{2}}{d^{2}} - 1)]}

$Z = "N" ^ 0.5 * "d" sqrt( "T" [1+ f( "A" )( "D" ^2/ "d" ^2 -1)])$

INPUTS

The inputs are as follows:

P - pitch (Hertz)
L - speaking length (inches)
d - core wire diameter (mils aka ${(\frac{1}{1000})}^{s}$ $(1/1000)^s$ of inches)
A - wrap wire material
D - total wire diameter (mils), and a - which is a unit-less coefficient.
