State whether the following is true or false.
An unsteady state balance reduces to the steady state form once the derivative becomes zero.

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

Answer: B

Setting the accumulation term to zero recovers the algebraic balance, so the steady state is the long time limit of the unsteady solution. Checking that limit is a useful test of a solution. The long time limit should match the algebraic answer.
