A Cylindrical Vessel Is Filled With Water To A Height H. A Vessel Has Two Holes In The Side, From Which Water Is Rushing Out Horizontally And Two Streams Strike At The Same Point. If The Lower Hole Q Is H Height Abve The Ground, Then The Height Of Hole P Above The Ground Will Be :

A horizontal tube has different cross-sectional areas at points A and B. The diameter of A is 4 cm and that of B is 2 cm. Two manometer limbs are attached at A and B. When a liquid of density 0.8 g/cm³ flows through the tube, the pressure-difference between the limbs of the manometer is 8 cm. calculate the rate of flow of the liquid in the tube. (g = 980 cm/s²)   

Find out the velocity of efflux of water from a hole in the wall of a tank made at 20 m below the free surface of water in the tank.

g = 10 m/s².

Water tank has a hole in its wall at a distance of 10 m below the free surface of water. The diameter of the hole is 2 mm. Compute the velocity of efflux of water from the hole and the rate of flow of water. (g = 9.8 m/s²) 

S₁ and S₂ are spring balances. A block A is hanging from spring balanceS₁ and immersed in a liquid L which is contented a beaker B. The mass of beaker B is 1 kg and the mass of liquid L is 1.5 kg. The S₁ and S₂balances reads 2.5 kg and 7.5 kg respectively. What will be the reading ofS₁ and S₂ when the block A is pulled up out of the liquid :
