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 Δp² Δp 2Δp Δp/2 Δp² Δp 2Δp Δp/2 ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics For Laminar flow through a packed bed, the pressure drop is proportional to (Vs is the superficial liquid velocity and Dp is the particle diameter) Vs²/Dp² Vs/Dp³ Vs²/Dp³ Vs/Dp² Vs²/Dp² Vs/Dp³ Vs²/Dp³ Vs/Dp² ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The normal stress is the same in all directions at a point in a fluid, when the fluid is Incompressible Both A and B Non-viscous Having no motion of one fluid layer relative to the other Incompressible Both A and B Non-viscous Having no motion of one fluid layer relative to the other ANSWER DOWNLOAD EXAMIANS APP
