Abstract
The lower bound for the passively advected flux is studied. It is comp letely rigorous and turns out to be close to, or of the order of magni tude of, the true value. The lower bound is obtained through the varia tional principle which incorporates the physical constraints-i.e., the conservation laws of the flux and the energy. It can be argued that t he same method can be applied to a variety of problems with physical i mplications.
