Example 1.1 Calculate the velocity gradient and the shear stress for y=0., 0.1, and 0.5m if the velocity profile of the flow between two parallel plates is a parabola given by u = 50 (2y-y²), 0≤ y ≤lm Where u is in (m/s) and y is in (m). Draw the shear stress distribution. Also calculate the frictional drag force of the fluid on the bottom boundary on an area of 10 m². Use dynamic viscosity μ-0.001 Pa-s.
