Air ( = 1 g/L , = 0.00002 Pa.s) flows through a packed bed of spheres of D = 0.01 m. The bed diameter = 1 m and = 0.4. The air velocity based on empty column is 1.5 kg/m2.s. What should the height of column be to have a pressure drop of 20,000 Pa?

Air ( = 1.5 g/L , = 0.000034 Pa.s) flows through a packed bed of spheres of D = 0.03 m. The bed diameter = 2 m and = 0.6. The air velocity based on empty column is 3.5 kg/m2.s. What should the height of column be to have a pressure drop of 40,000 Pa?
