Question: n-Butyl alcohol at 60F flows between two parallel plates w1 th the velocity given by vx(y)=vmax[1(y/B)2]. If vmax=7in/s and B=4 in, find the shear stress

n-Butyl alcohol at 60F flows between two parallel plates w1 th the velocity given by vx(y)=vmax[1(y/B)2]. If vmax=7in/s and B=4 in, find the shear stress (lbf/ft2) at y=0,1,2,3 and 4 inches. Plot the shear stress vs. y. Find the frictional force on the bottom plate (y=B) for a length L=1ft and a width W=1ft (in the z-direction)
