Hydraulics and Fluid Mechanics in ME Whenever a plate is held immersed at some angle with the direction of flow of the liquid, it is subjected to some pressure. The component of this pressure, in the direction of flow of the liquid, is known as Lift Drag Bulk modulus Stagnation pressure Lift Drag Bulk modulus Stagnation pressure ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The point in the immersed body through which the resultant pressure of the liquid may be taken to act is known as center of pressure center of gravity center of buoyancy metacentre center of pressure center of gravity center of buoyancy metacentre ANSWER DOWNLOAD EXAMIANS APP

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 Power required (in watts) to drive a centrifugal pump is (where Hm = Manometric head in metres, w = Specific weight in N/m3, Q = Discharge of the pump in m3/s, and ηo = Overall efficiency of the pump) (w Q) / (Hm × ηo) (w Q ηo) / Hm (w Hm) / (Q × ηo) (w Hm Q) / ηo (w Q) / (Hm × ηo) (w Q ηo) / Hm (w Hm) / (Q × ηo) (w Hm Q) / ηo ANSWER DOWNLOAD EXAMIANS APP
