1.	Which of the following system follows the differential equation?(a) Semi- Batch process(b) Batch process(c) Fed- Batch process(d) Continuous processThis question was addressed to me during an interview.I would like to ask this question from Law of Conservation of Mass topic in portion Material Balance of Bioprocess Engineering
Answer» The correct choice is (d) Continuous process Explanation: Amounts of mass entering and leaving the system are specified USING flow rates, a mass balance based on rates is called a differential balance. WHEREAS, each term of the mass-balance equation in this case is a quantity of mass, not a RATE. This type of balance is called an integral balance. Differential balances for continuous SYSTEMS operating at steady state and integral balances for batch and semi-batch systems between INITIAL and final states are used.
