Find the ratio of distillate to residual flow rates, if a binary mixtu...
Given Data:
- Mixture composition: 65% more volatile component
- Distillate composition: 90%
- Residue composition: 30%

Calculating the ratio of distillate to residual flow rates:

Step 1: Calculate the amount of more volatile component in the distillate and residue
- In the distillate: 90% of 65% (mixture composition) = 58.5%
- In the residue: 30% of 65% (mixture composition) = 19.5%

Step 2: Calculate the ratio of distillate to residue flow rates
- Let the distillate flow rate be D and the residue flow rate be R
- D + R = 100 (total flow rate)
- D/58.5 = R/19.5 (ratio of more volatile component in distillate to residue)
Solving the above equations simultaneously, we get:
- D = 78.4
- R = 21.6
- Ratio of D to R = 78.4/21.6 ≈ 2.4
Therefore, the ratio of distillate to residual flow rates is 2.4. This means that for every 2.4 units of distillate produced, 1 unit of residue is obtained.
