Question

A settling chamber is measuring 6 meters in length, 3 meters in width, and 1.5 meters in height. The air stream flowrate entering the chamber is 17 m3/s, and the average particle size (diameter) is 65 micrometers. Assume a particle density of 1800 kg/m3 and that Stokes law applies.

Some properties of air:

Atmospheric pressure = 101.4 kPa = 14.7 psi

Air density = 1.2 kg/m3.

Air viscosity = 1.85x 10^-5 Pa.s.

1. the air stream horizontal velocity in the chamber in m/s.
2. the particle settling velocity in m/s.
3. the particulate matter removal efficiency of the settling chamber.
