C-101: Parallel opposed cylinders of unequal radius and equal finite length.

Reference: Juul (1982)

Definitions:

R = r₁/r₂; L = l/r₂; C = c/r₂

Governing Equations: Use A-E in regions noted on chart below

Tabulated Values are obtained by numerical integration.  The view factors in the blank regions may be calculated by the equations with an error less than 1%.
