	According to Bernoulli's equation $\frac{P}{\rho g}+h+\frac{1}{2}\,\frac{{{v}^{2}}}{g}=\text{constant}$. The terms $A$, $B$ and $C4 are generally called respectively:
	At what speed the velocity head of a stream of water be equal to 40 cm of Hg
	The weight of an aeroplane flying in air is balanced by
	In this figure, an ideal liquid flows through the tube, which is of uniform cross-section. The liquid has velocities${{v}_{A}}$ and ${{v}_{B}}$, and pressure $P_A$ and $P_B$ at points $A$ and $B$ respectively
	A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross-section ${{A}_{1}}$ and ${{A}_{2}}$, are ${{v}_{1}}$ and ${{v}_{2}}$ respectively. The difference in the levels of the liquid in the two vertical tubes is h
	A sniper fires a rifle bullet into a gasoline tank making a hole $53.0 m$ below the surface of gasoline. The tank was sealed at $3.10 atm$. The stored gasoline has a density of $660 kgm^{–3}$. The velocity with which gasoline begins to shoot out of the hole is
	An L-shaped tube with a small orifice is held in a water stream as shown in fig. The upper end of the tube is 10.6 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 m/s
	Fig. represents vertical sections of four wings moving horizontally in air. In which case the force is upwards
	An L-shaped glass tube is just immersed in flowing water such that its opening is pointing against flowing water. If the speed of water current is v, then
	A tank is filled with water up to a height H. Water is allowed to come out of a hole P in one of the walls at a depth D below the surface of water. Express the horizontal distance x in terms of H and D
