Question $4$: Consider the following steady, incompressible, two$-$dimensional velocity field:

$\frac{?}{\text{b}\text{a}\text{r}}(V)=(u,v)=(0\mathrm{.}5+1\mathrm{.}2x)hat()+(-2-1\mathrm{.}2y)hat()$

Generate an analytical expression for the flow streamlines and draw several streamlines in the

upper$-$right quadrant from $x=0$ to $5$ and $y=0$ to $6.$

Generate a velocity vector plot in the upper$-$right quadrant from $x=0$ to $5$ and $y=0$ to $6.$
