Fqra cold viscous feed, backward feed gives _____________ than forward feed?
Correct answer: A. A higher capacity
- A. A higher capacity
- B. A lower capacity
- C. Lower economy
- D. None of these
Explanation
For a cold, viscous feed, backward feed sends the more concentrated liquid to the hotter effect, where its viscosity decreases and heat transfer improves. It therefore generally gives a higher capacity than forward feed.
