For a gas cyclone, feed particle size distribution weights across ranges sum to 20.0g and collected solids weights sum to 13.8g (same sampled duration). What is the collection efficiency (in PERCENTAGE) of the gas cyclone?

  • A31
  • B60
  • C65
  • 69

Explanation

Overall collection efficiency = total collected / total feed × 100 = 13.8/20.0×100=69%.
