Figure shows a conical vessel having its outlet at A to which a U-tube manometer is connected. The reading of the manometer indicated in the figure pertains to the situation when the vessel is empty, i.e. the water surface is at A. Find the reading of the manometer when the vessel is completely filled with water.
Correct answer is 'Range: 42 to 44'. Can you explain this answer?

Figure shows a conical vessel having its outlet at A to which a U-tub...
Case (a) when the vessel is empty Equating pressure values at the points 1 and 2 which lie at the same horizontal plane; patm + (13.6 × 9810 × 0.2) = 9810 × h + Patm
∴ h = 13.6 × 9810 × 0.2 / 9810
= 2.72 m
For case (b) when the vessel is full of water: Let the mercury level fall by a distance δ in the right limb with a corresponding rise δ in the left limb. Again writing the governing manometric equation for the points 1′ and 2′:
Patm + 13.6 × 9810 × (0.2 + 2δ)
= 9810 (3 + 2.72 + δ) + Patm
Solution gives: δ = 0.1145 m Hence the manometer reading would be
0.20 + 2 × 0.1145 = 0.429 m
= 42.90 cm
