Question

Water flows steadily from an open tank as shown in the figure. (Figure 1) The elevation of point 1 is 10.0 m, and the elevation of points 2 and 3 is 2.00 m. The cross-sectional area at point 2 is 4.80 × 10^-2m²; at point 3, where the water is discharged, it is 1.60 ×  10^-2m². The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe.

Part B
