Question

What is the value of B?

(a) 18.9 mole/hr

(b) 38.6 mole/hr

(c) 45.2 mole/hr

(d) 72.1 mole/hr

The question was posed to me in an internship interview.

This question is from Recycle without Chemical Reaction topic in chapter Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

Correct answer is (b) 38.6 mole/hr

To elaborate: Overall NaCl balance: 100*0.05 = B*0.12 + P*0.01, => 12B + P = 500, => B = 38.6 mole/hr.
