Infinite cylinder to infinite cylinder of different radius
Function f2d_9(r_1,r_2,s) returns the view factor from an infinitely long cylinder of radius r_1 to a parallel infinitely long cylinder of radius r_2.
Inputs:
r_1 = the radius of the emitting cylinder [m or ft]
r_2 = the radius of the recieving cylinder [m or ft]
s = the distance between the cylinders measured from the closest points [m or ft]
Example:
$UnitSystem SI K Pa J deg
r_1=0.1 [m]
r_2=0.2 [m]
s=1 [m]
F = f2d_9(r_1,r_2,s)
{Solution:
F=0.04922}
