Function SF_28(d_in, d_out, L, N) returns the shape factor for conduction between an N-sided polygon shaped hole that is centered inside a circular extrusion.
The calling protocol is:
S= SF_28(d_in, d_out, L, N)
d_in = diameter of the circle inscribed within the polygon [m or ft]
d_out = diameter of the extrusion [m or ft]
L = length of the extrusion [m or ft]
N = number of sides [-]
S shape factor [m or ft]
