Following figure shows the flow of liquid through a horizontal pipe. Three tubes$A, B$ and $C$ are connected to the pipe. The radii of the tubes $A, B$ and $C$ at the junction are respectively $2 \mathrm{cm}, 1 \mathrm{cm}$ and $2 \mathrm{cm}.$ It can be said that the

A manometer connected to a closed tap reads $3.5\times {10}^5\mathrm{ }\mathrm{N} {\mathrm{m}}^{-2}$. When the valve is opened, the reading of manometer falls to $3.0\times {10}^5\mathrm{ }\mathrm{N} {\mathrm{m}}^{-2}$, then velocity of flow of water is 

Water flows through a frictionless duct with a cross-section varying as shown in the figure. Pressure $P$ at points along the axis is represented by

An ideal fluid is flowing through the given tubes which is placed on a horizontal surface. If the liquid has velocities $V_{\mathrm{A}}$ and $V_{\mathrm{B}},$ and pressures $P_{\mathrm{A}}$ and $P_{\mathrm{B}}$ at points $A$ and $B$ respectively, then the correct relation is ($A$ and $B$ are at the same height from ground level, the figure shown is as if the system is seen from the top)

An L-shaped tube with a small orifice is held in a water stream as shown in the figure. The upper end of the tube is $10.6 \mathrm{cm}$ above the surface of water. What will be the height of the jet of water coming from the orifice? (Velocity of water stream is $2.45 \mathrm{m} {\mathrm{s}}^{-1}$).

The tube shown in the figure is of uniform cross-section. Liquid flows through it at a constant speed in the direction shown by arrows. Then the liquid exerts(on the tube) is

Water from a tap emerges vertically downwards with an initial velocity $V_0.$ Assume pressure is constant throughout the stream of water and the flow is steady, find the distance from the tap at which cross-sectional area of stream is half of the cross-sectional area of stream at the tap:

As shown in the figure a liquid of density $\rho$ is standing in a sealed container to a height $h$. The container contains compressed air at a gauge pressure of $p$. The horizontal outlet pipe has a cross-sectional area$\frac{A}{2}$at $E$. Find the correct options.
