Question: A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross-section ${{A}_{1}}$ and ${{A}_{2}}$, are ${{v}_{1}}$ and ${{v}_{2}}$ respectively. The difference in the levels of the liquid in the two vertical tubes is h

Question Image

1) The volume of the liquid flowing through the tube in unit time is ${{A}_{1}}{{v}_{1}}$
2) ${{v}_{2}}-{{v}_{1}}=\sqrt{2gh}$
3) $v_{2}^{2}-v_{1}^{2}=2gh$
4) The energy per unit mass of the liquid is the same in both sections of the tube
Solution: Explanation: No Explanation
Fluid Flow
