360895 A liquid flows through a horizontal tube as shown in figure. 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 \(h\). Then
