An incompressible (1D) steady-state flow in a circular diffuser is flowing from station 1 at x1 = 0 (where the velocity is u = 3 m/s) to station 2 at x2 = 10 cm. The inlet radius at station 1 is r1 = 5 cm and at station 2 the radius is r2 = 10 cm. Calculate the fluid acceleration as a function of x.
