Outer surface of a small cylinder to the inner surface of a large cylinder when the small cylinder extends beyond the large cylinder on one end



Function f3d_25(x,y,l,r1,r2) returns the view factor between the outer surface of a small cylinder to the inner surface of a large cylinder when the small cylinder extends beyond the large cylinder on one end.

Inputs:
x = distance that small cylinder extends on the left [m or ft]
y = length of large cylinder [m or ft]
l  = length of small cylinder [m or ft]
r1 = radius of the smaller cylinder [m or ft]
r2 = radius of the larger cylinder [m or ft]

Example: 
$UnitSystem SI K Pa J deg
x=0.1 [m]
y=0.2 [m]
l=0.1 [m]
r1=0.05 [m]
r2=0.1 [m]
F = f3d_25(x,y,l,r1,r2)

{Solution: F=0.1603}
