This is a problem in batch processing of materials using a mixing tank. The mixing tank has inflow and outflow tubes and a stirrer that keeps the concentration uniform at all points in the tank. The tank is initially filled by a volume V of solution, formed by dissolving a given solute in a solvent, with concentration C0 (measured in kg/l); The inflow tube carries a solution of different concentration Cin than the initial concentration; the volumetric flowrate is Qin The outflow flowrate is Qout and, due to the well-mixed assumption, the outflow concentration has the same concentration as the instantaneous concentration of the tank. (i) Derive the differential equation governing the instantaneous concentration in the tank.
