A non-viscous liquid of constant density 500 kg/m^3 flows in a variable cross-sectional tube. The area of cross section of the tube at two points P and Q at heights of 3 m and 6 m are 2 × 10^−3 m^3 and 4 × 10^−3 m^3, respectively. Find the work done per unit volume by the forces of gravity as the fluid flows from point P to Q.

As Fig. shows, S1 and S2, are spring balances. Block A is hanging from spring balance S1 and immersed in liquid L which is contained in beaker B. The mass of beaker B is 1 kg and mass of liquid L is 1.5 kg. Balances S1 and S2 reads 2.5kg and 7.5kg, respectively. What will be the readings of S1 and S2 when block A is pulled up out of the liquid. Find the reading of S1 and `S_(2)?
