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