List of top Physics Questions on Bernauli Theorem asked in NEET (UG)

Water flows in a streamline motion through a horizontal pipe of circular cross-section as shown in the figure. The pressure difference of water between \(P\) and \(Q\) is \(15\,\text{N m}^{-2}\). The area of cross-section at \(P\) and \(Q\) are \(40\,\text{cm}^2\) and \(20\,\text{cm}^2\), respectively. The rate of flow of water through the pipe, in \(\text{cm}^3\text{s}^{-1}\), is:

In a u-tube as shown in figure, water and oil are in the left side and right side of the tube respectively. The heights from the bottom for water and oil columns are 15 cm and 20 cm respectively. The density of the oil is :- [take \(\rho_{water}\) = 1000 kg/m\(^3\)]
