Rectangular floor to a circular end wall segment



Function f3d_56(b,c,theta) returns the view factor between a rectangular floor and an endwall that is a circular segment.

Inputs:
b = half-width of floor [m] or [ft]
c = length of floor [m] or [ft]
theta = angle between floor and center of end wall [degree] or [radian]

Example: 
$UnitSystem SI Mass J K Pa Degree
b=1 [m] 
c=1 [m]
theta=50 [degree]
F=f3d_56(b,c,theta)

{Solution:
 F=0.1009}
