SF_10
Function SF_10 provides the shape factor ([m] or [ft]) for conduction between a cylinder that is positioned between two parallel plates. The plates have infinite width and equal length to the cylinder. The cylinder is positioned midway between the plates.
Inputs:
D = diameter of cylinder ([m] or [ft])
w = distance from cylinder axis to plate ([m] or [ft])
L = length of wall and plates ([m] or [ft])
Example: SF = SF_10(D, w, L)

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo D, w, L, SF units=m
D = 0.1 [m]
w = 0.2 [m]
L = 1 [m]
SF = SF_10(D, w, L)
{Solution:
SF = 3.86 [m]}
