SF_26
Function SF_26 provides the shape factor ([m] or [ft]) for radial conduction through a hollow sphere.
Inputs:
r_in = inner radius of sphere ([m] or [ft])
r_out = outer radius of sphere ([m] or [ft])
Example: SF = SF_26(rin, rout)

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo r_in, r_out, SF units=m
r_in = 0.1 [m]
r_out = 0.2 [m]
SF = SF_26(r_in, r_out)
{Solution:
SF = 2.513 [m]}
