Problem: Water flows steadily from an open tank as shown in the figure. (Figure 1) The elevation of point 1 is 10.0m, and the elevation of points 2 and 3 is 2.00 m. The cross-sectional area at point 2 is 4.80x102m; at point 3, where the water is discharged, it is 1.60x102m. The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe. Part A Assuming that Bernoulli's equation applies, compute the volume of water ΔV that flows across the exit of the pipe in 1.00 s. In other words, find the discharge rate ΔV/Δt. Express your answer numerically in cubic meters per second.
