Question

In a small column, local efficiency is equal to Murphree efficiency, and in a large column, local efficiency is:

• A. Equal to, less than
• B. Equal to, more than
• C. Less than, equal to
• D. Less than, more than

Hint:

Column diameter significantly impacts efficiency due to axial mixing.

Answer 1

The Correct Option is A

In small columns, local efficiency is approximately equal to Murphree efficiency due to minimal axial mixing. In large columns, axial mixing reduces local efficiency compared to Murphree efficiency.
