Avelocity field is given by where x and y are in feet (u and v are in ft/s). (a) plot the one streamline that passes through the point: x 0 and y-0. (b) explain how you figure out the direction of flow along this one streamline. [hint, pay attention to when x and y are positive or negative, or when the streamline crosses either axis.] (c) what might be going on at the origin?
