Solve the following problems. Important: Write down from which tables and figures all the data you use in the solutions are obtained. Also, specify all the assumptions that you make in the solutions. 1. Ammonia is absorbed in water from a mixture with air using a column operating at atmospheric pressure and 295K. The resistance to transfer can be regarded as lying entirely in a gas film 1mm thick. At a point in the column the partial pressure of the ammonia is 6.6 kN/m2 a) What is the transfer rate per unit area at that point in the column? b) If the gas was compressed to 200kN/m2 pressure, how would the transfer rate will be altered?
