An experiment on the growth rate of certain organisms requires an environment of humid air en-

riched in oxygen. Three input streams are fed into an evaporation chamber to produce an output

stream with the desired composition.

A:

B:

C:

Liquid water, fed at a rate of 20.0 cm/min

Air (consider as 1 mol of air do not separate as N2 and O2 )

Pure oxygen, with a molar flow rate one-fifth of the molar flow rate of stream B

The output gas is analyzed and is found to contain 1.5 mole% water. Draw and label a flowchart of

the process, and calculate all unknown stream variables.
