2. Water enters a 0.05m diameter tube at section #1 at an average speed of 0.5 m/sand exits through station #2 and #3, as shown. The diameter of the exit

at station #2is 0.03m 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 0.02m.
