Q: Consider water flows between two parallel fix plates at 20C (dynamic viscosity =0.001 Pa.s). The velocity distribution for the flow is given by, u-10(0.01 Y-Y2) m/s, where (Y= meter) from the lower wall as shown in Figure, determine (1) the shear stress at the wall. (2) The shear stress at a distance of (2 mm) from the wall.
