The flow and mixing patterns in this system are studied by dissolving 1500 g of a salt (S) in the first tank, and then starting the 40 L/s flow through the system. Each tank outlet stream is monitored with an on-line thermal conductivity detector calibrated to provide instantaneous readings of salt concentration. The data are plotted versus time, and the results are compared with the plots that would be expected if the tanks are all perfectly mixed. Your job is to generate the latter plots. a) assuming that pure water is fed to the first tank and that each tank is perfectly mixed (so that the salt concentration in a tank is uniform and equal to the concentration in the outlet stream from that tank), write salt balances on each of the three tanks, convert them to expressions for dCS1 /dt, dCS2 / dt, and dCS3 / dt, and provide appropriate initial conditions.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
