The transfer function which relates the exiting temperature T to the inlet concentration c A i is to be derived. All the assumptions made during the derivation are to be stated. Approximate this transfer function by first-order approximation and the validity of this approximation is to be compared with the step responses of both the models, original and approximate. Concept introduction: For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances. The process models generally include algebraic relationships which commence from thermodynamics , transport phenomena , chemical kinetics, and physical properties of the processes. The difference in the actual variable ( y ) and the original variable ( y ¯ ) is known as deviation variable ( y ′ ) . It is generally used while modelling a process. Mathematically it is defined as: y ′ = y − y ¯ In steady-state process, the accumulation in the process is taken as zero.
