Ammonia is to be absorbed from an air mixture at 323 K and 1.048 x 10-5 pascal pressure in a counter-current packed tower using water at 323 K as the absorbent. An inlet gas rate of 1.97 x 10-2 m3/s and an ammonia-free water rate of 7.87 x 10-3 kg/s will be used.If the ammonia concentration is reduced from 5.49 vol% to 2.15 vol%, determine the following.
