Disk to concentric ring that is parallel.
Function f3d_62(a,r_1,r_2,r_3) returns the view factor between a disk and a concentric, parallel ring.
Inputs:
a = distance from disk to ring [m] or [ft]
r_1 = radius of disk [m] or [ft]
r_2 = inner radius of ring [m] or [ft]
r_3 = outer radius of ring [m] or [ft]
Example:
$UnitSystem SI Mass J K Pa Radian
a=0.3 [m]
r_1=0.15 [m]
r_2=0.1 [m]
r_3=0.2 [m]
F= f3d_62(a,r_1,r_2,r_3)
{F = 0.4867}
