Problem $3.$ The fluid flowing above the plate $($as shown in picture$)$ has an absolute viscosity of

$0\mathrm{.}0010lb*\frac{s}{f}{t}^2$ and specific gravity of $0\mathrm{.}913,$ calculate the velocity gradient $(d\frac{v}{d}y)$ and intensity of

shear stress at the boundary and at points $1$ in$.,2$ in $.,$ and $3$ in $.$ from the boundary assuming a

straight$-$line velocity distribution.
