PhysicsHardsingle choice

Water flows in a horizontal pipe whose one end is closed with a valve. The reading of the pressure gauge attached to the pipe is $P_{1}$ . The reading of the pressure gauge falls to $P_{2}$ when the valve is opened. The speed of water flowing in the pipe is proportional to

Options:

Answer:

Solution:

Using Bernoulli's theorem $P_{1} - P_{2} = \frac{1}{2} ρ v^{2} v \propto P_{1} - P_{2}$
