A flow of moist air at 45ºC, 20% relative humidity with a flow rate of 0.2 kg/s is mixed with a flow of moist air at 25ºC and absolute humidity of ω = 0.018 kg/kg of air with a rate of 0.3 kg/s dry air. The mixing takes place in an air duct at 100 kPa, and there is no significant heat transfer. After the mixing, there is heat transfer to a final temperature of 40ºC. Find the temperature and relative humidity after mixing. Find the heat transfer and the final relative humidity.

Question
A flow of moist air at 45ºC, 20% relative humidity with a
flow rate of 0.2 kg/s is mixed with a flow of moist air at 25ºC
and absolute humidity of ω = 0.018 kg/kg of air with a rate of
0.3 kg/s dry air. The mixing takes place in an air duct at 100
kPa, and there is no significant heat transfer. After the mixing,
there is heat transfer to a final temperature of 40ºC. Find the
temperature and relative humidity after mixing. Find the heat
transfer and the final relative humidity. Use the provided
psychrometric chart. Label all states clearly on the
psychrometric chart and show all
You must upload the psychrometric chart.
