Pick out the correct relationship. (Where, Ri = internal reflux ratio Ro = external reflux ratio.) ?
Correct answer: A. (1 + Ro) = Ro/Ri
- A. (1 + Ro) = Ro/Ri
- B. (1 - Ro) = Ro/Ri
- C. (1 + Ri) = Ro/Ri
- D. (1 - Ri) = Ro/Ri
Explanation
For a total condenser, the internal reflux ratio is Ri = Ro/(1 + Ro), where Ro is the external reflux ratio. Rearranging gives 1 + Ro = Ro/Ri.
