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 16 mm/s 12 mm/s 28 mm/s 24 mm/s 16 mm/s 12 mm/s 28 mm/s 24 mm/s ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics In case of hydraulically smooth pipe, the resistance to flow depends only on the Reynolds number, whereas for a hydraulically rough pipe, the resistance to flow is governed by the relative roughness. Two pipes are said to have the same hydraulic roughness, when they have equal values of Friction co-efficient for flows at equal Reynold number All of these Absolute roughness Relative roughness Friction co-efficient for flows at equal Reynold number All of these Absolute roughness Relative roughness ANSWER DOWNLOAD EXAMIANS APP
