Question

The rate of flow through an opening due to the wind blowing on the wall containing it is given by the expression ___________

(a) Q = KV/A

(b) Q = KA/V

(c) Q = AV/K

(d) Q = KAV

I have been asked this question in class test.

I would like to ask this question from Air Conditioning topic in chapter Acoustics and Ventilation of Construction & Building Materials

Answer 1

Correct answer is (c) Q = AV/K

Explanation: The rate of flow through an opening due to the wind blowing on the wall containing it is given by the expression where Q = rate of air flow in m^3/h, A = area of the smaller opening in square metres, K is the coefficient of effectiveness and V is the wind speed in m/h.
