The practical representative values of HETP for a number of commercial operations lies within a range of ______________ metre?
Correct answer: C. 0.4-0.9
- A. 0.1-0.2
- B. 0.2-0.5
- C. 0.4-0.9
- D. 1.2-1.5
Explanation
For commercial tray and packing operations, practical HETP values commonly fall around 0.4 to 0.9 m. Much smaller values are difficult to achieve commercially, while values above 1 m indicate relatively poor contacting performance.
