Fluid Mechanics A bed of spherical particles (specific gravity 2.5) of uniform size 1500 μm is 0.5 m in diameter and 0.5 m high. In packed bed state, the porosity may be taken as 0.4. Ergun's equation for the above fluid-particle system (in SI units) is given below : Δ P/L = 375 x 10³ VOM + 10.94 x 10⁶ V²OM (SI units) If water is to be used as the fluidising medium, the minimum fluidisation velocity, VOM is 12 mm/s 16 mm/s 28 mm/s 24 mm/s 12 mm/s 16 mm/s 28 mm/s 24 mm/s ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will Remain unchanged Data insufficient to predict relative pressure drop Increase Decrease Remain unchanged Data insufficient to predict relative pressure drop Increase Decrease ANSWER DOWNLOAD EXAMIANS APP

Fluid Mechanics Select the wrong statement pertaining to flow of an incompressible fluid through a venturimeter. Discharge of fluid through a venturimeter depends upon the gage difference irrespective of the orientation of venturimeter For frictionless flow, the fluid pressure entering the venturi meter will be exactly equal to that leaving the venturimeter Venturimeter incurs less power loss compared to an equivalent orificemeter Venturimeter occupies less space than an orificemeter Discharge of fluid through a venturimeter depends upon the gage difference irrespective of the orientation of venturimeter For frictionless flow, the fluid pressure entering the venturi meter will be exactly equal to that leaving the venturimeter Venturimeter incurs less power loss compared to an equivalent orificemeter Venturimeter occupies less space than an orificemeter ANSWER DOWNLOAD EXAMIANS APP
