143238 A water pump, rated $400 \mathrm{~W}$, has an efficiency of $\mathbf{7 5 \%}$. If its is employed to raise water through a height of $40 \mathrm{~m}$, the volume of water drawn in 10 $\min$ is-

143239 A tank is filled with a liquid upto a height $H$. A small hole is made at the bottom of this tank. Consider $t_{1}$ be the time taken to empty first half of the tank and $t_{2}$ be the time taken to empty rest half of the tank. Then, determine the ratio $t_{1} / t_{2}$.

143240 A tank is filled with water. There is a hole in the bottom. At the bottom total pressure is 3 atm $\left(1 \mathrm{~atm}=10^{5} \mathrm{~N} / \mathrm{m}^{2}\right)$, then, the velocity of water flowing from hole is-

143241 A water pump of power $2 \mathrm{~kW}$ is installed in a home. Then, the amount of water (in litres) it can raise in one minute to a height of $10 \mathrm{~m}$ is [Take $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}$ ]
