Sphere to disk

Function F3D_16(r, h) returns the view factor between a sphere (surface 1) located on a line that is normal to the center of a disk (surface 2).

Inputs:

r = radius of the disk [m or ft]

h = distance between the center of the sphere and the center of the disk [m or ft]

Example:  

$UnitSystem SI K Pa J rad

r=1 [m]

h=0.5 [m]

F=F3D_16(r, h)

{Solution: F=0.2764}
