Annular rings at the ends of an inscribed cylinder
Function F3D_66(r_c,r_1,r_2,h) returns the view factor between annular rings at the ends of an inscribed cylinder.
Inputs:
r_c = radius of inner cylinder [m] or [ft]
r_1 = outer radius of annular ring [m] or [ft]
r_2 = radius of outer cylinder [m] or [ft]
h = height of cylinder [m] of [ft]
Example:
$UnitSystem SI Mass J K Pa Radian
r_c=0.1[m]
r_1=0.3 [m]
r_2=0.2 [m]
h=0.5 [m]
F=F3D_66(r_c,r_1,r_2,h)
{Solution
F=0.1413}
