일반물리학 1 — Fluids: Problem 37

37 The intake in Fig. 14-36 has cross-sectional area of \(0.740 \text{ m}^2\) and water flow at \(0.400 \text{ m/s}\). At the outlet the cross-sectional area is smaller than at the intake and the water flows out at \(9.50 \text{ m/s}\). The pressure difference between intake and outlet is \(3.00 \text{ MPa}\). What is vertical distance \(D\)?
