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 4.80×10−2 m2 ; at point 3, where the water is discharged, it is 1.60×10−2 m2 . The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe. Figure1 of 1 The figure shows an open water-filled tank on a stand. Point 1 is on the water surface 10 meters above the ground. The water flows out of the tank through a descending pipe. Point 2 is on the horizontal ending part of the pipe 2 meters above the ground. Point 3 is the exit 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 .
