The following stream function is an exact solution to the Navier-Stokes equations and represents the steady, planar flow of a viscous, Newtonian, incompressible fluid of dynamic viscosity, ji, approaching a flat plate: where A and B are known constants. The following is a sketch of the flow J-1- plate Neglecting gravity, evaluate: a. the velocity of the flow in terms of 4. B. x, and y, b. the vorticity in the flow in terms of A. B. x. and y. c. the shear stress on the plate as a function of y (also indicate the direction), and d. the shear force on that portion of the plate between )=0 and y=1 per unit depth into the page c. Can we write a potential function for this flow? Explain your
