Answer

The flow rate of the outlet liquid stream is approximately 210 lb/hr.

The flow rate of the outlet vapor stream is approximately 140 lb/hr. 

Discussion

With an outlet vapor pressure of 50 psig, the percent difference between the inlet liquid flow rate and the outlet liquid flow rate is approximately 6%. One should note that some of the air dissolved in the water and contributed to this difference.
