Question 5 8 Points A two-bed carbon adsorption system is to be designed to handle 8000 acfm of air containing 700 ppm of hexane. Laboratory studies indicate that carbon can adsorb

8 lb hexane per 100 lb carbon under the conditions at which the system will be operated (net adsorption). If the system is to operate at 90 °F and 1 atm and flow velocity of 100 ft/min, determine the diameter of each carbon bed (in ft). Bed regeneration and cooling will require one hour. Assume carbon density is 25 lb/ft³. The bed depth should be at least 1 ft. Add your answer Integer, decimal, or E notation allowed
