SOLUTIONS OF THE NEWTONIAN VISCOUS-FLOW EQUATIONS 211 PROBLEMS 3-1. Reconsider the problem of Couette flow between parallel plates, Fig. 3-1, for a power-law nonnewtonian fluid, Txy = K(du/dy)", where n + 1. Assuming constant pressure and temperature, solve for the velocity distribution u(y) between the plates of (a) n < 1 and (b) n > 1, and compare with the newtonian solution, Eq. (3-6). Comment on the results.
