The dynamic response of a stirred-tank bioreactor can be represented by the transfer function where C is

Question:

The dynamic response of a stirred-tank bioreactor can be represented by the transfer function

where C is the exit substrate concentration, mol/L and C_f is the feed substrate concentration, mol/L.

(a) Derive an expression for c?(t) if c_P(t) is a rectangular pulse (figure) with the following characteristics:

(b) What is the maximum value of c?(t)? When does it occur1 What is the final value of c?(t?

(c) If the initial value is c(0) = 1, how long does it take for c(t) to return to a value of 1.05, after it has reached its maximum value?
