Industrial humidifiers has two inlet streams – 1. liquid waterand 2. drier air. The entering liquid water stream flows at 5.31mol/min. The component flow rate of air in the drier air stream is44.3 mol/min. The exiting streams consist of a wetter air streamand a liquid water stream. The exiting liquid water stream contains34.5% of the entering liquid water. The outlet streams are in vaporliquid equilibrium at 42.8oC and 786 mmHg.
a) Draw the process flow diagram, number the streams, and label thespecies in each stream.
b) Find the component mass flow rates (kg/min) of all fourstreams.
c) The pressure of the outlet streams decrease by 5%, will the molefraction of water in the wetter air increase, decrease, stay thesame? Justify your answer.
