For the inviscid steady flow field given by$$V$=-$ky i $+$ kx j which is a model of the flow inside a tornado, evaluate the pressure gradient in the x direction in Pa$/$m at a point where x $=49\mathrm{.}0$ m$,$ y $=44\mathrm{.}0$ m$,$ and k $=1\mathrm{.}451/$s$.$ Assume the fluid is air with density of $1\mathrm{.}2$ kg$/$m$3.$
