Figure shows a siphon. Choose the wrong statement:
($P_0$ = atmospheric pressure)
Siphon works when $h_3 > 0$
Pressure at point $2$ is $P_2 = P_0 - \rho gh_3$
Pressure at point $3$ is $P_0$
None of the above
Explain why roof of building flyout during stormy wind.
In this figure, an ideal liquid flows through the tube, which is of uniform cross-section. The liquid has velocities${v_A}$ and ${v_B}$, and pressure $P_A and P_B$ at points $A$ and $B$ respectively
Write Bernoulli’s principle in word.
The cross sectional area of a horizontal tube increases along its length linearly, as we move in the direction of flow. The variation of pressure, as we move along its length in the direction of flow ($x-$ direction), is best depicted by which of the following graphs
