  • In this paper. the principle of maximum power losses for the incompressible viscous fluid proposed by professor Chien Wei-zang is extended to the hydrodynamic problems of a special class of non-Newtonian fluid——generalized Newtonian fluid.The constraint condition of variation are eliminated by the method of idetified Lagrangian multipliers and a generalized variational principle is established.
