A Flow carries an inflow concentration, Cin, into a one compartment model with a given Volume. Cin is constantly and instantaneously well mixed becoming C, the concentration in the compartment. C empties out of the compartment and is designated Cout. G is a clearance rate. For a constant concentration of inflowing material the analytic solution is given.

Analytic Solution when Cin(t) is constant
