The figure shows a liquid of density ρ flowing through a tube with velocity v. The h1 and h2 are the heights of liquid in the straight and L-shaped tubes, respectively. Choose the correct statements.
- The pressure at the point A is ρgh1
- The pressure at the point B is ρgh2
- The velocity of flow is, \(\mathrm{v}=\sqrt{2 \mathrm{gh}_{2}}\)
- The velocity of flow is, \(\mathrm{v}=\sqrt{2 \mathrm{~g}\left(\mathrm{~h}_{2}-\mathrm{h}_{1}\right)}\)
Answer
(D) The velocity of flow is, v = 2 ~g ( ~h _ 2 - h _ 1 )
