    A tank is filled with water. There is a hole in . the bottom. At the bottom total pressure is 3 aim, then, the velocity of water flowing from h\[\left( \text{1atm }=\text{1}{{0}^{5}}\text{ N}/{{\text{m}}^{\text{2}}} \right)\],then, the velocity of water flowing from hole is

    A) 10m/s                  

    B) 20m/s

    C) 15m/s                  

    D) 25m/s

    Correct Answer: B

    Solution :

    At bottom of tank \[p=h\rho g=3\times {{10}^{5}}N/{{m}^{2}}\] Pressure due to liquid column                                  \[{{p}_{1}}=3\times {{10}^{5}}-1\times {{10}^{5}}=2\times {{10}^{5}}\] Velocity of water \[V=\sqrt{2gh}\] \[v=\sqrt{\frac{2{{p}_{1}}}{\rho }}=\sqrt{\frac{2\times 2\times {{10}^{5}}}{{{10}^{3}}}}\] \[=20m/s\]
