Ammonia is being absorbed in a tower using pure water at 25 °c and 1.0 atm abs pressure. the feed rate is 1440 ibm/h and contains 3.0 mol% ammonia in air. liquid to gas mass flow rate gl/gg= 2/1 and use of 1-in metal pall rings.

a) calculate the pressure drop in the packing and gas mass veplocity at flooding. using 50% of the flooding velocity, calculate the pressure drop, gas and liquid flows, and tower diameter.
