$1)$ a fluid flowing over a flat surface with an upstream

flow velocity of V$\backslash$infty $=2$ m$/$s$.$ A suction pump is used to channel water through an

opening with a volume flow rate $($per unit length$)$ of $0\mathrm{.}05$ m$2/$s$.$ Determine the location of the stagnation point $\text{'}$S$\text{'}$ on the flat surface. The stagnation point is measured relative to the location of the sink. Also, Determine the minimum distance $$ above the flat surface $($upstream of the sink$),$ such that water will not get sucked into the opening. Explain both answers.
