QJEEM24Ph95d5: JEE Main 2024 Physics - Class 11 JEEM24Ph95d5 Solution: The reading of pressure metre attached with a closed pipe is…

The reading of pressure metre attached with a closed pipe is $$4.5\times {10}^4\mathrm{N}/{\mathrm{m}}^2$$. On opening the valve, water starts flowing and the reading of pressure metre falls to $$2.0\times {10}^4\mathrm{N}/{\mathrm{m}}^2$$. The velocity of water is found to be $$\sqrt{V}\mathrm{m}/\mathrm{s}$$. The value of $$V$$ is _________.
