There is a cylindrical tube fully filled with small spherical particles. A processing gas at room condition (30 C) is going through this tube and it is expected to have a pressure drop of 0.1 atm. Assuming that the air viscosity is slightly higher i.e. 0.02 mPa.s, calculate the specific surface of the bed and the air linear circulation velocity. Given that: The tube is 180 cm height and 15 cm diameter. The radius of the small particles is approximately 1 mm with density of 1 g/cm³. The total mass of the particles in the tube is approximately 5000 g. A pressure drop of 0.1 atm was measured (Let R=0.082 atm.m³/kmol.K).
