Unformatted text preview: assume that in that region the flow is essentially incompressible and inviscid, and the radial velocity component |v r | is small compared with the circumferential velocity component. (a) Show, by applying the angular momentum theorem to a control volume comprising the water between r = r and r = R , that the angular velocity at r is v = VR r . (b) Demonstrate that the assumption |v r | << v is satisfied if b << R ....
