Dry gas containing 65% air and 45% ammonia vapor enters the bottom of a cylindrical tower that is 3.6 feet in diameter. the entering temperature at the bottom of the tower is 80 °f, and the exiting temperature of the gas is 60 °f. the tower operates at 760 mmhg. water enters from the top of the tower to absorb ammonia. ammonia absorbed into the liquid water leaves at the bottom of the tower, while the remaining ammonia vapor leaves from the top of the tower. the leaving gas contains 0.09% ammonia. part a) if the entering gas flows through the empty bottom of the column at 0.75 m/s, how many cubic feet of ammonia are entering the column? part b) how many pounds of ammonia are absorbed by the water per hour? (note: density of ammonia cannot be neglected) part c) under similar conditions, recalculate part b, with methane instead of ammonia and an temperature of 100 °f and a leaving gas stream of 50 °f, all other conditions remaining the same. entering gas state all assumptions clearly.
