When a pipe flow suddenly expands from Aj to A2,low-speed, low-friction eddies appear in the cornersand the flow gradually expands to A2 downstream.Using the suggested control volume (enclosed by theblue dashed lines) and assuming that the pressureacting on the annular ring is approximately P , showthat under the assumption that the flow isincompressible the pressure downstream isP, = P, + pv?
