SF_6

Function SF_6 provides the shape factor  ([m] or [ft])for conduction between the external surfaces of a beam buried in a semi-infinite medium.

Inputs:

 a = width of beam (parallel to surface) ([m] or [ft])

 b = thickness of beam (perpendicular to surface) ([m] or [ft])

 w = depth of beam (surface to top of beam) ([m] or [ft])

Example:  SF = SF_6(b, a, w, L)
