Question 47
MNNAT2 marksNeeds review
Polluted air with particulate matters of diameter 50 μm enter with a horizontal velocity of 1.0 m/s at a height of 0.5 m from the bottom of a dry settling chamber. The density of the particle is 200 kg/m³ and dynamic viscosity of the air is 1.8 × 10⁻⁵ kg/m-s.
Assume streamline flow and the density of air is negligible as compared to particles and uniform horizontal velocity of 1.0 m/s of gas and particles within the chamber.
Considering particle setting follows Stoke’s law, the minimum length in m, of the chamber required for setting of the particle at its bottom is _____. (round off up to 2 decimals)
