An exothermic reaction A ---B takes place in the tanks below. It is given as the rate expression A A r kC for the reaction. Accordingly, by making necessary assumptions, derive the model equations describing the following system in the form of differential equations.

Note 1: The volumetric velocity at the first tank outlet is proportional to the square root of the liquid level of the tank.

Note 2: Heat capacity can be taken constant for all streams in the temperature ranges given.
