Q23.The reading of pressure metre attached with a closed pipe is 4 . 5 × 104 N m-2. On opening the valve, water starts flowing and the reading of pressure metre falls to 2 . 0 × 104 N m-2. The velocity of water is found to be √𝑉 m s-1. The value of 𝑉 is _________.
What This Question Tests
This question is a direct application of Bernoulli's principle for a horizontal pipe to calculate the velocity of water flow based on the observed pressure difference.
