A. Tank filling with no outlet
B. Well-mixed washout
C. Batch reactor
D. Semi-batch reactor
List II
1. accumulation equals the generation term
2. accumulation equals the inlet flow
3. accumulation equals inlet plus generation
4. accumulation equals minus the outlet term

  • A.A-4, B-2, C-1, D-3
  • B.A-2, B-4, C-3, D-1
  • C.A-3, B-1, C-4, D-2
  • D.A-2, B-4, C-1, D-3

Answer: D

Each case keeps a different subset of the general balance, and identifying which terms survive is the whole of setting the problem up. The integration that follows is then a matter of technique. Identifying the surviving terms is the real work.
