The equation of a velocity distribution over a plate is given by u = 2y - y2 + 20. Assuming μ = 8.00 poise, the shear stress all the boundary and shear stress at a point 15 cm from the boundary in N/m2
1
1.6 at the boundary and 1.36 at 15 cm from the boundary
2
2.6 at the boundary and 20.6 at 15 cm from the boundary
3
3.6 at the boundary and 24.6 at 15 cm from the boundary
4
1.8 at the boundary and 14.6 at 15 cm from the boundary
