1. Air at 20°C and atmospheric pressure flows horizontally through a collection chamber 3 m high and 5 m long. The air carries particles 70 µm diameter, with a specific gravity of 1.5. What is the maximum air speed that can be used to ensure that all particles have settled out in the chamber?
2. Air at 60°F and atmospheric pressure flows horizontally at a speed of 1 f t/s through a collection chamber 12 ft high. The air carries particles 0.002 in. diameter, with a specific gravity of 2.0. What is the minimum length of the chamber necessary to ensure that all particles are collected?
