$(2)$ Empirical Transport Laws and Their Units

$($a$)$ For the one$-$dimensional form of Newton's Law of Viscosity ${}_{yx}=-\frac{d{v}_x}{dy}$ give the units

of each symbol in the equation in both the SI system $,$ and $s$ and the British system $,$

$ft,$ and $s).$ Then show that the equation is dimensionally consistent.
