In a two-dimensional, incompressible flow field, the x component of velocity is given by the equation u = 2x. (a) Determine the corresponding equation for the y component of velocity if v = 0 along the x axis. (b) For this flow field, what is the magnitude of the average velocity of the fluid crossing the surface OA of Fig. P6.16? Assume that the velocities are in feet per second when x and y are in feet.
