Air flows through a packed bed of a powdery material of 2 cm depth at a superficial gas velocity of 1 cm/s. A manometer connected to the unit registers a pressure drop of 2 cm of water. The bed has a porosity of 0.6. If Burke -Plummer equation is valid for the range of study, estimate the particle diameter size of the powder. Data: Pair = 1.23 kg/m, Pwater = 1000 kg/m, g = 9.8 m/s and = 1. a) D=4.0610 m b) D=5.0610 m c) D, = 6.0610% m d) D=8.0610 m Air flows through a packed bed of a powdery material of 2 cm depth at a superficial gas velocity of 1 cm/s.
