SF_11
Function SF_11 provides the shape factor ([m] or [ft]) for conduction between the inner and outer surfaces of a circular rod with an eccentric circular hole.
Inputs:
d_in = diameter of eccentric inner cylinder ([m] or [ft])
D_out = diameter of bounding cylinder ([m] or [ft])
w = distance between cylindrical axes ([m] or [ft])
L = length of tube ([m] or [ft])
Example: SF = SF_11(d_in, D_out, w, L)

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo d_in, D_out, w, L, SF units=m
d_in = 0.1 [m]
D_out = 0.3 [m]
w = 0.05 [m]
L = 1 [m]
SF = SF_11(d_in, D_out, w, L)
{Solution:
SF = 6.529 [m]}
