simple air purifier is designed to remove tiny particles in the air. In order not to scarify the

air flow, a pressure drop of 0.25 atm is permissible. Determine the air velocity if the air purifier

(1.5 m height, 0.2 m diameter) is fully packed with activated carbons (5 mm side, total mass of

1200g, density of 1 g/cm3
). Given that the R=0.082 atm.m3
/kmol.K, and the viscosity of the air

is 2.1 x10-5 Pa.s.
