1.	An unsteady state system, the flow in rate of A is 10 mole/s, what is the flow out rate of B if the accumulation was 10 mole in 2 seconds?(a) 5 mole/s(b) 10 mole/s(c) 15 mole/s(d) 20 mole/sI have been asked this question during an interview for a job.Query is from Steady-State and Unsteady-State Systems topic in section Introduction to Material Balances of Basic Chemical Engineering
Answer» Correct ANSWER is (a) 5 mole/s Explanation: Flow RATE of B = 10 – 10/2 = 5 mole/s.
