.: A fluid with density p is flowing through a bend in a rectangular cross-section duct. The radius of the inner surface of duct is R, and the outer surface radius is R. The velocity distribution is a function of the radial coordinate, r, and is given by V = Ar, where A is a constant. If the inner wall pressure is P, determine the pressure on the outer wall of the duct in terms of R1, R, A, p, and P Assume that the flow is incompressible, inviscid and steady. P V=Ar R R
