1.Draw a graph showing the effluent concentration as a function of time for: a) Zero order CMFR (completely mixed flow reactor) and PFR(plug flow reactor) with the same influent concentration andreaction rate. b) First order CMFR and PFR with the same influent concentration and reaction rate. c) In each pairing, which type of reactor requires the longest meanretention time?
2.An offshore drilling rig is being towed out to sea. What is the maximum distance away that the navigation lights can still be seen by an observer standing at the shoreline? The observer's eye height is 5'6" and the uppermost navigation light is 168 above the water.
