The amount of mass transported via a pipe over a period of time can be computed as M = Q(t)c(t)dt t1 Where M = mass (mg), ti = initial time (min), t2 = the final time (min) and c(t) = concentration (mg/m). The flow rate Q can be computed as: Q = 9 + 4e-0.05t2 And the concentration was measured at different times from 0 to 15 min as in table below: 2 5 8. 11 15 Time (min) 0. 4.5 4.6 6.7 10.4 19 5.4 C(t), mg/m By the use of best combination of integration formulas, determine the mass transported between ti =0 and t2 = 15 min.
