F3D_70

Cylinder inner surface to an adjacent surface on the same cylinder

Function f3d_70(r_c,r,s,h_1,h_2) returns the view factor between a cylinder inner surface to an adjacensurface on the same cylinder

Inputs:
r_c = radius of inner cylinder [m] or [ft]
r = radius of outer cylinder [m] or [ft]
s = distance between the two cylinder sections ring [m] or [ft]
h_1 = height of first cylinder section [m] of [ft]
h_2 = height of second cylinder section [m] of [ft]

Example:
$UnitSystem SI Mass J K Pa Radian
r_c=0.5 [m]
r=1 [m]
s=0.1 [m]
h_1=0.25 [m]
h_2=0.5 [m]
F=f3d_70(r_c,r,s,h_1,h_2)

{Solution
F=0.09284}
