5. Water flows steadily from an open tank as in the figure below. The elevation of point 1 is 10.0m, and the elevation of points 2 and 3 is 2.00m. The cross-sectional area at point 2 is 0.0480m 2 ; at point 3 it is 0.0160m 2. The area of the tank is very large compared with the cross-sectional area of the pipe.
