Problem 1 Consider the problem of Couette flow between parallel plates for a power-law nonnewtonian fluid 74, = K (du/dy)", where n # 1. Assuming constant pressure and temperature, solve and sketch the velocity distribution u(y) between the plates «form <1 «form="">1 « compare with the newtonian fluid solution Problem 2 Consider the problem of Couette flow of two immiscible fluids between parallel plates. Fluid 1 with viscosity 1 is located from y=-h to y=0. Fluid 2 with viscosity izis located from y=0 to y=h. Assuming constant pressure and temperature, solve and sketch the velocity distribution u(y) between the plates if ©
