Assignment:
Air at 373 K and 2 atm is passed through a bed 10 cm in diameter composed of iodine spheres 0.7 cm in diameter. The air flows at a rate of 2 m/s, based on the empty cross section of the bed. The porosity of the bed is 40%.
(a) How much iodine will evaporate from a bed 0.1 m long? The vapor pressure of iodine at 373 K is 6 kPa.
(b) Estimate the pressure drop through the bed.
Provide complete and step by step solution for the question and show calculations and use formulas.
