This is because when a particle on a streamline reaches a point, , further on that streamline the equations governing the flow will send it in a certain direction . As the equations that govern the flow remain the same when another particle reaches a 0 {\displaystyle a_{0}} it will also go in the direction x → {\displaystyle {\vec {x}}} .
