A fluid with a density of 2000 kg/m³
flows steadily between two flat plates as shown in Fig. P6.30. The bottom plate is fixed and the top one moves at a constant speed in the x direction. The velocity is
 where y is in meters. The acceleration of gravity is

Use the x and y components of the equations of motion (Eqs. 6.50a and b) to determine the normal stress throughout the fluid. Assume that
