A cylindrical column contains a bed of spherical solid particles with a total bed height of 1.5 meters. The density of the solid particles is 1500 kg/m³ and the diameter of the particles is 0.05 meters. Air is used as the fluidizing medium. Determine the minimum fluidization velocity required to fluidize the bed. Given: Void fraction (ε) = 0.4 Dynamic viscosity of air (μ) = 1.8 × 10-5 kg/(m·s) Density of air (ρ₀) = 1.2 kg/m³ Use this and quadratic equations to solve the problem
