Infinite Parallel Plates of Differing Widths with Common Centerline



Function f2d_10(a, b, c) returns the view factor between two infinitely long, directly opposed parallel plates that can have different widths.

Inputs:
a is the distance between the plates [m or ft]
b is the width of the plate 1  [m or ft]
c is the width of plate 2  [m or ft]

Example:  
$UnitSystem SI K Pa J deg
a=1 [m]
b=1 [m]
C=2 [m]
F=f2d_10(a, b, c)

{Solution: 
F=0.6847} 


This function is more general than f2d_1 in that it allows the plates to have different widths.  It can also be applied if the widths are the same.
