Consider a $2-$D flow field formed by combining two sources of equal strength $m.$ The sources are located at $(0,-1)$ and $(0,1).(15\%)$

$($a$)$ Locate the stagnation point in this flow field.

$($b$)$ Determine the streamline equation passing through the stagnation point in the Cartesian coordinate.

$($c$)$ Assume the total pressure in the flow field is $P_0$ and the density of the fluid is $,$ find the static pressure at the point $(1,0).$
