State whether the following is true or false.
A tank whose level is constant is necessarily at steady state in every respect.

  • A.False
  • B.True only at large scales
  • C.False only at small scales
  • D.True

Answer: A

The total mass may be constant while the composition inside still changes with time, as in a washout. Steady state must hold for every species and for energy, not merely for the total inventory. A washout is exactly such a case.
