A chemical process is said to occur under unsteady state, if the_________________?
Correct answer: B. Flow rates & composition both are time dependent
- A. Inventory changes do not take place
- B. Flow rates & composition both are time dependent
- C. Ratio of streams entering/leaving are independent of time
- D. None of these
Explanation
An unsteady-state process has process variables that change with time, such as flow rates or stream compositions. Here, both flow rates and compositions are stated to be time-dependent.
