Fluid Mechanics A 2" gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is Δp² Δp < Δp > Δp Δp² Δp < Δp > Δp ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The bulk modulus of elasticity of a liquid Is zero for incompressible liquid Increases with pressure Is independent of temperature & pressure Decreases with pressure Is zero for incompressible liquid Increases with pressure Is independent of temperature & pressure Decreases with pressure ANSWER DOWNLOAD EXAMIANS APP

Fluid Mechanics Water hammer is caused, when water flowing in a pipe is suddenly brought to rest by closing the valve. The extent of pressure thus produced due to water hammer depends on the Time taken to close the valve Pipe length Fluid velocity in the pipe All of these Time taken to close the valve Pipe length Fluid velocity in the pipe All of these ANSWER DOWNLOAD EXAMIANS APP
