Water enters a 0.05-m-diameter tube at section 1 at an average speed of 0.5 m/s and exits through stations 2 and 3, as shown. The diameter of the exit at station 2 is 0.03 m and the average velocity there is 0.5 m/s. as well. Calculate the average exit velocity at station 3 if the tube diameter there is 0.02 m.
