A closed pipe containing liquid showed a pressure ' $P_{1}$ ' by guage. When the valve is opened, pressure was reduced to ' $P_{2}$ '. The speed of water flowing out of the pipe is $[ρ =$ density of water $]$

Options:

Answer:

Solution:

(B) By Bernoulli equation, $∴ ∴ v P_{1} = P_{2} + \frac{1}{2} ρ v^{2} P_{1} - P_{2} = \frac{1}{2} ρ v^{2} = \frac{2 ( P _{1} - P _{2} )}{ρ}$
