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 as ΔP/L = 375 x 10 V + 10.94 x 10 V (SI units). If water is to be used as the fluidising medium, the minimum fluidisation velocity, V is
