Fluid Mechanics The normal stress is the same in all directions at a point in a fluid, when the fluid is Incompressible Non-viscous Having no motion of one fluid layer relative to the other Both A and B Incompressible Non-viscous Having no motion of one fluid layer relative to the other Both A and B ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be Δp/2 Δp² 2Δp Δp Δp/2 Δp² 2Δp Δp ANSWER DOWNLOAD EXAMIANS APP
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
