The velocity distribution for flow over a plate is given by u = 0.5y – y2 where ‘u’ is the velocity in m/s at a distance ‘y’ meter above the plate. lf the dynamic viscosity of the fluid is 0.9 N-s/m2, then what is the shear stress at 0.20 m from the boundary?
1
0.9 N/m2
2
1.8 N/m2
3
2.25 N/m2
4
0.09 N/m2
