Determine the shape factor between a small area and a parallel circular disc A2(diameter D) is located on the axis of the disc and the semi-vertex angle of the cone formed with the disc as base and as the vertex is α.
Option~
(A)
(B)
(C)
(D)
Correct answer is 'A'. Can you explain this answer?

Determine the shape factor between a small area and a parallel circul...
Considering an elementary ring dA2 of width dr at a radius r,
dA2 = 2 πr dr
Now, r = L tanΦ1
Dr = L sec2Ф11
dA2 = 2πL2 tan Φ1 sec2 Φ11
L/P = cos Φ1 or P = L/cosΦ1
= sin2 α = D2/4/D2/4 + L2 = D2/D2 + 4L2
where D is the diameter of the disc.
