Conditioned air at 13°C and 90 percent relative humidity is to be mixed with outside air at 34°C and 40 percent relative humidity at 1 atm. If it is desired that the mixture has a relative humidity of 60 percent, determine (a) the ratio of the dry air mass flow rates of the conditioned air to the outside air, (b) the temperature of the mixture, and (c) check your results by the psychrometric chart. Note: do not use the psychrometric chart for calculation.

use the principles of psychrometrics 

Conditioned air at 13°C and 90 percent relative humidity is to be mixed with outside air at 34°C
and 40 percent relative humidity at 1 atm. If it is desired that the mixture has a relative humidity
of 60 percent, determine (a) the ratio of the dry air mass flow rates of the conditioned air to the
outside air, (b) the temperature of the mixture, and (c) check your results by the psychrometric
chart. Note: do not use the psychrometric chart for calculation.
