A circular cone of diameter D with a length L is positioned on a common axis with a circular disk, also of diameter D, at a distance L (Fig. P21€“65). A cylindrical surface of diameter D with a length L and a circular disk, of the same diameter D, are oriented coaxially at a distance L. Determine the view factors F₁₂for the two geometries. Which of the two geometries has the higher view factor value?
