Write the limitation and uses of Bernoulli’s equation.

Does it matter if one uses gauge instead of absolute pressures in applying Bernoulli’s equation? Explain.

Figure shows a siphon. Choose the wrong statement:

($P_0$ = atmospheric pressure)

Write limitations of Bernoulli’s theorem.

The Pitot tube shown in the figure is used to measure fluid flow velocity in a pipe of cross sectional area $S$. It was invented by a French engineer Henri Pitot in the early $18^{th}$ century. The volume of the gas flowing across the section of the pipe per unit time is (The difference in the liquid columns is $\Delta h,  \rho_0$ and  $\rho$  are the densities of liquid and the gas respectively) :-

A cylindrical vessel containing a liquid is rotated about its axis so that the liquid rises at its sides as shown in the figure. The radius of vessel is $5\, cm$ and the angular speed of rotation is  $\omega\; rad \,s^{-1}$. The difference in the height, $h($ in $cm )$ of liquid at the centre of vessel and at the side will be
