1.	From the following type of processes, which type depends on the steady-state condition?(a) Batch process(b) Fed-Batch process(c) Semi-Batch process(d) Continuous processI got this question during an interview.The query is from Thermodynamic Preliminaries in section Material Balance of Bioprocess Engineering
Answer» The correct answer is (d) Continuous process The explanation is: If all properties of a SYSTEM, such as temperature, pressure, concentration, volume, MASS, etc. do not vary with time, the process is said to be at steady state. Continuous processes MAY be either steady state or transient. It is USUAL to RUN continuous processes as close to steady state as possible; however, unsteady-state conditions will exist during start-up and for some time after any change in operating conditions.
