Coaxial Finite Parallel Square Planes of Differing Edge Length
Function F3D_20(a, b, c) returns the view factor between two finite parallel squares having the same center.
Inputs:
a = edge length for square 1 [m or ft]
b = edge length for square 2 [m or ft]
c = distance between squares [m or ft]
Example:
$UnitSystem SI K Pa J rad
a=0.1 [m]
b=0.2 [m]
c=0.2 [m]
F=F3D_20(a, b, c)
{Solution: F=0.1167}
F3D_20 calls the more general F3D_14 to do the calculations.
