An ideal fluid flows between the inclined walls of a two dimensional channel into a sink located at the origin (Fig. P6.33). The velocity potential for this flow field is

where m is a constant. (a) Determine the corresponding stream function. Note that the value of the stream function along the wall OA is zero. (b) Determine the equation of the streamline passing through the point B, located at x = 1, y = 4.
