The dynamic response of a stirred-tank bioreactor can be represented by the transfer function C′ (s) C′ F(s) = 4 2s + 1 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 cF(t) is a rectangular pulse (Fig. 5.2) with the following characteristics: cF(t) = ⎧ ⎪ ⎨ ⎪ ⎩ 2 t < 0 4 0 ≤ t < 2 2 2 ≤ t < [infinity] (b) What is the maximum value of c′ (t)? When does it occur? 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? 5.5 A th

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
