According to the Balances on steady-state processes, the accumulation

1.	According to the Balances on steady-state processes, the accumulation is equal to?(a) 1(b) 0(c) 100(d) 2I had been asked this question by my college director while I was bunking the class.I need to ask this question from Material Balance Numericals in division Material Balance of Bioprocess Engineering
Answer» Correct answer is (b) 0 Easy explanation: The process is said to be operating at steady-STATE when all process variables do not CHANGE with time. The accumulation term in a balance must equal to ZERO to ENSURE that the amount/mass of material in the process do not change with time. Steady state means accumulation = 0 Input + generation – output – CONSUMPTION = 0 Input + generation = output + consumption.
