The rate of material _____________ is zero in case of a steady state system?
Correct answer: A. Accumulation
- A. Accumulation
- B. Production
- C. Input
- D. Generation
Explanation
At steady state, the amount of material inside the system does not change with time, so the accumulation term in the material balance is zero. Input, production, and generation may still be nonzero if they are balanced by output, consumption, or destruction.
