Question

For rectangular ducts, the aspect ratio is equal to *
(A) sum of longer and shorter sides
(B) sum of longer and shorter sides
(C) product of longer and shorter sides
(D) ratio of longer and shorter sides

Answer 1

Answer:

(C) product of longer and shorter sides

Explanation:

For rectangular ducts, the aspect ratio is equal to product of longer and shorter sides

Answer 2

(D) The ratio of longer and shorter sides is the correct answer to the given question.

• As we know that the aspect ratio is the ratio of width to height.
• And the width is larger than the height in the aspect ratio.
• As the rectangular ducts have been determined by using an analogy with the stress function of the theory of elasticity.
• Hence, for the rectangular ducts, the aspect ratio is equal to the ratio of longer and shorter sides.
