BIL108 Introduction to Scientific and Engineering Computing Spring08 Midterm Exam 2 A1. The following equation pertains to the concentration of a chemical in a well mixed reactor.   0.04t 0.04t in 0 C C 1 e C e If the initial concentration 0 C 4 and the inlet concentration in C 10 , develop an m-file that solves for t within a tolerance of 0.5 % or in less than 20 iterations, for C to be 93% of in C . A2. Three disease carrying organisms decay exponentially in seawater according to the following model.   1.5t 0.3t 0.05t p t Ae Be Ce Estimate the initial concentration of each organism (A, B and C) given the following measurements. t 0.5 1 2 3 4 5 6 7 8 9 p(t) 7 5.2 3.8 3.2 2.5 2.1 1.8 1.5 1.2 1.1 A3. The amount of mass transported via a pipe over a period of time can be computed as     2 1 t t M Q t c t dt Where M = mass (mg), t 1 = the initial time (min), t 2 = the final time (min), Q(t) = flow rate (m 3 /min) and
