SF_1
Function SF_1 provides the shape factor ([m] or [ft]) for a sphere that is completely buried in a semi-infinite medium:
Inputs:
D = diameter of sphere ([m] or [ft])
w = depth of sphere (surface to center line) ([m] or [ft])
Example: SF = SF_1(D, w)

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo D, w, SF units=m
D=0.5 [m]
w=2 [m]
SF = SF_1(D, w)
{Solution:
SF = 3.351 [m]}
