4. Develop the mass balance equation found in Table 2.6 for: (1) the steady-state, completely mixed model with reaction decay and (2) the three-compartment steady state model with reaction decay. Start from the mass balance equation assuming a first-order decaying substance and steady input concentration, Cin. Solve for CCin. Assuming k=1.0, why does the three-compartment model result in a lower outflow concentration from an equal volume lake?
