143292 Water flows through a horizontal pipe of variable cross-section at the rate of $20 \mathrm{~L} \mathrm{~min}^{-1}$. What will be the velocity of water at a point where diameter is $\mathbf{4} \mathbf{c m}$ ?

143293 At what speed will the velocity of a stream of water be equal to $20 \mathrm{~cm}$ of mercury column? (Taking, $g=10 \mathrm{~ms}^{-2}$ )

143294 A large vessel with a small hole at the bottom is filled with water and kerosene with kerosene floating on water. The length of water column is $20 \mathrm{~cm}$ and that of kerosene is $25 \mathrm{~cm}$. The velocity with which water flows out of the hole is
(density of kerosene $=0.8 \mathrm{~g} \mathrm{~cm}^{-3}$, neglect viscous force).

143295 A block of density $\rho=800 \mathrm{~kg} / \mathrm{m}^{3}$ floats face down in a liquid of density $1200 \mathrm{~kg} / \mathrm{m}^{3}$. The block is $6 \mathrm{~cm}$ high. Calculate the depth $h$ of the block submerged in the liquid.
