Which of the followings is a wrong statement?

The shape factor is equal to one

Detailed Solution for Test: Shape Factor - Question 1

For a flat or convex surface, the shape factor with respect to itself is zero. This aspect stems from the fact that for any part of flat or convex surface, one cannot see any other part of the same surface.

Test: Shape Factor - Question 2

Establish a relation for the shape factor of cylindrical cavity with respect to itself of depth h and diameter d. The cavity is closed on its outer surface with a flat plate

Detailed Solution for Test: Shape Factor - Question 2

F 11 + F 12 = 1 and F 21 + F 22 = 1. But F 22 = 0, so F 11 = 1 – A 2 / A 1.

Two radiating surface A 1 = 6 m2 and A 2 = 4 m2 have shape factor F 12 = 0.1. Then the shape factor F 21 will be
Detailed Solution for Test: Shape Factor - Question 4

A 1 F 12 = A 2 F 21.

Test: Shape Factor - Question 5
Save

What is the value of shape factor for two infinite parallel surfaces separated by a distance x?
Detailed Solution for Test: Shape Factor - Question 5

All the radiation emitted by one falls on the other so shape factor is unity.

Test: Shape Factor - Question 6
Save

What is the shape factor of a sphere of diameter d inside a cubical box of length l = d?
Detailed Solution for Test: Shape Factor - Question 6

F 11 + F 12 = 1 or F 12 = 1. So, F 21 = π/6.

Test: Shape Factor - Question 7
Save

What is the shape factor of hemispherical surface closed by a plane surface of diameter d?
Detailed Solution for Test: Shape Factor - Question 7

F 11 + F 12 = 1 and F 21 = 1. Therefore, F 11 = 0.5.

Test: Shape Factor - Question 8
Save

What is the shape factor of hemispherical surface closed by a plane surface of diameter d?
Detailed Solution for Test: Shape Factor - Question 8

F 11 + F 12 = 1 and F 21 = 1. Therefore, F 11 = 0.5.

Test: Shape Factor - Question 9

Establish a relation for shape factor for a conical cavity with respect to itself of depth h and diameter d. The cavity is closed on its outer surface with a flat plate
Detailed Solution for Test: Shape Factor - Question 9

F 11 = 1 – A 2 / A 1 = 1 – 2 sin α = 1 – d/ (4 h 2 + d 2) ½.

Test: Shape Factor - Question 10
Save

What is the shape factor for a hemispherical bowl with respect to itself of diameter d? The cavity is closed on its outer surface with a flat plate
Detailed Solution for Test: Shape Factor - Question 10

F 11 = 1 – A 2 / A 1 = 0.5.

Test: Shape Factor - Question 11
Save

Consider a system of concentric spheres of radius r 1 and r 2 (r 2 is greater than r 1). If r 1 = 5 cm, determine the radius r 2 if it is desired to have the value of shape factor F 21 equal to 0.6
Detailed Solution for Test: Shape Factor - Question 11

From reciprocity theorem, A 1 F 12 = A 2 F 21.
