The velocity distribution for flow over a flat plate is given by $$u = (y - y^2)$$ in whichu is velocity in metres per second at a distance y metres above the plate. What is the shear stress value at y = 0.15 m ? The dynamic viscosity of fluid is 8.0 poise.

A

12.4 N/m$$^2$$

B

1.24 N/m$$^2$$

C

0.56 N/m$$^2$$

D

5.6 N/m$$^2$$
