To determine The height up to which the liquid will bubble up in the rotameter. Explanation Write the expression for the Bernoulli equation. P 1 ρ g + V 1 2 2 g + Z 1 = P 2 ρ g + V 2 2 2 g + Z 2 (I) Here, the pressure at state 1 is P 1 , the pressure at state 2 is P 2 , the velocity at state 1 is V 1 , the velocity at state 2 is V 2 the elevation at state 1 is Z 1 the elevation at state 2 is Z 2 , the density is ρ and the acceleration due to gravity is g . Write the expression for the velocity. V = Q A (II) Here, the discharge is Q and the area is A . Write the expression for the discharge for rotameter. Q = k × S R (III) Here, the scale reading is S R and the constant is k . Conclusion: The state 1 is considered at the exit of rotameter and state 2 is considered at the entry of rotameter. Substitute P a t m for P 1 , P a t m for P 2 , 0 for V 2 and 0 for P 2 , 0 for h L , 0 for Z 1 in Equation (I). P a t m + V 1 2 2 g + 0 = P a t m + 0 + Z 2 + 0 V 1 2 2 g = Z 2 (IV) Substitute k × S R for Q , in Equation (II)

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
