Hydraulics and Fluid Mechanics in ME The flow in a pipe or channel is said to be non-uniform when The liquid particles at all sections have the same velocities Each liquid particle has a definite path The quantity of liquid flowing per second is constant The liquid particles at different sections have different velocities The liquid particles at all sections have the same velocities Each liquid particle has a definite path The quantity of liquid flowing per second is constant The liquid particles at different sections have different velocities ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME When a piping system is made up primarily of friction head and very little of vertical lift, then pump characteristics should be First rise and then fall Nearly horizontal Horizontal Steep First rise and then fall Nearly horizontal Horizontal Steep 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
Hydraulics and Fluid Mechanics in ME A vertical wall is subjected to a pressure due to one kind of liquid, on one of its sides. The total pressure on the wall per unit length is (where w = Specific weight of liquid, and H = Height of liquid) wH2/3 wH/2 wH2/2 wH wH2/3 wH/2 wH2/2 wH ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME In a single casing, multistage pump running at constant speed, the capacity rating is to be slightly lowered. It can be done by Trimming the impeller size to the required size by machining Not possible Designing new impeller Some other alterations in the impeller Trimming the impeller size to the required size by machining Not possible Designing new impeller Some other alterations in the impeller ANSWER DOWNLOAD EXAMIANS APP
