1. An experiment on the growth rate of certain organisms requires an environment of humid air enriched in oxygen. Three input streams are fed into an evaporation chamber to produce an output stream with the desired composition which are Liquid water, fed at a rate of 20,0 cm/min Air (21 mole% O2, the balance N) Pure oxygen, with a molar flow rate one-fifth of the molar Row rate of air in stream (1) a The output gas is analysed and is found to contain 1.5 mole% water. (a) Perform the degree of freedom analysis and determine if there is enough information to solve the problem (20 marks) (b) Calculate all the unknown for all the streams. (30 marks)
