Question

A gravity settling chamber of height ‘H' and length ‘L' is designed to control particulate air pollution. In the chamber, the horizontal velocity of air flow is $'V_h'$ and terminal settling velocity of the target particle is $'V_ť$. Which one of the following expressions is the correct concept used to calculate the minimum size of the target particle that will be removed with 100% efficiency?

• A. \(\frac{V_t}{L} = \frac{V_h}{H} \)
• B. \({V_h}\times {V_t} = L \times H\)
• C. \({V_h} = V_t \times L \times H\)
• D. \(\frac{V_t}{H} = \frac{V_h}{L}\)

Answer 1

The Correct Option is D

The correct answer is (C) : $H_2S$
