2. A composition analyzer is used to measure the concentration of a pollutant in a wastewater stream. The model relating the measured composition and the actual composition is given by the following transfer function C, (s) C'(s) 1 %3D TS +1 where t= 5 min. At steady state, ē= C = 3 ppm. A warning light on the analyzer turns on when the measured concentration exceeds 10 ppm. Suppose the actual concentration begins to increase at a rate of c(t) = 3 + 0.5t where c(t) is in ppm and t is in minutes. When will the warning light turn on? What is the actual concentration when the warning light turns on?
