Hydraulics and Fluid Mechanics in ME When a cylindrical vessel, containing some liquid, is rotated about its vertical axis, the liquid surface is depressed down at the axis of its rotation and rises up near the walls of the vessel on all sides. This type of flow is known as Turbulent flow Steady flow Uniform flow Vortex flow Turbulent flow Steady flow Uniform flow Vortex flow ANSWER DOWNLOAD EXAMIANS APP

Hydraulics and Fluid Mechanics in ME A flow in which the viscosity of fluid is dominating over the inertia force is called Unsteady flow Steady flow Laminar flow Turbulent flow Unsteady flow Steady flow Laminar flow Turbulent flow ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME An open tank containing liquid is made to move from rest with a uniform acceleration. The angle 0 which the free surface of liquid makes with the horizontal is such that (where a = Horizontal acceleration of the tank, and g = Acceleration due to gravity) tanθ = a/g tanθ = 2 a/g tanθ = a2/2g tanθ = a/2g tanθ = a/g tanθ = 2 a/g tanθ = a2/2g tanθ = a/2g ANSWER DOWNLOAD EXAMIANS APP
