Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly contracted to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden contraction, assuming coefficient of contraction as 0.62, is v₂²/2g v₁²/2g 0.375 v₂²/2g 0.5 v₁²/2g v₂²/2g v₁²/2g 0.375 v₂²/2g 0.5 v₁²/2g 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 Steady flow Vortex flow Turbulent flow Uniform flow Steady flow Vortex flow Turbulent flow Uniform flow ANSWER DOWNLOAD EXAMIANS APP
