Write the mass balance equation for a completely mixed lake with an impulse input of mass,M, added at time t=0. Assume the lake is of constant volume, V, with continuous outflow, Q, and a conservative substance. Solve for the outlet concentration in terms of the initial concentration Co, the mean hydrualic detention time (T), and time t. Plot the concentration C/Co versus t/T. How long does it take for 95% of the impulse input of material to be depleted from the system?
