Consider the streamlines over a circular cylinder as sketched at thefigure 3.26. single out the first three streamlines flowing over the topthe cylinder. designate each streamline by its stream function, vivianav3. the first streamline wets the surface of the cylinder, designate vanthe streamline above that is v2, and the next one above that is v3.assume the streamlines start out in the freestream equally spaced. hencethe volume flow rates between the streamlines are the same. thestreamline v2 passes through the point (1.2r,1/2) directly above the topof the cylinder. calculate the location of the point directly above the top ofthe cylinder through which the streamline y3 flows. comment on thespacing between the streamlines directly above the top.
