Question
A steady flow of water passes along a horizontal tube from a wide section X to the narrower section Y, see figure. Manometers are placed at P and Q at the sections. Which of the statements A, B, C, D, E is most correct?
- water velocity at X is greater than at Y
- the manometer at P shows lower pressure than at Q
- kinetic energy per
of water at X = kinetic energy per at Y
- the manometer at P shows greater pressure than at Y
of water at X = kinetic energy per at Y
The correct answer is: the manometer at P shows greater pressure than at Y

The vessel shown in the figure has two sections. The lower part is a rectangular vessel with area of cross-section A and height h. The upper part is a conical vessel of height h with base area ‘A’ and top area ‘a’ and the walls of the vessel are inclined at an angle 30° with the vertical. A liquid of density r fills both the sections upto a height 2h. Neglecting atmospheric pressure
