At 0°C, 60% relative humidity, the air entering with 2.2 m3/s comes out with 30°C, 50% relative humidity. In this air handling unit, the air at 10°C temperature and 60% relative humidity from the outside is blown inside at 30°C temperature and 50% relative humidity, after heating and humidification processes. The total pressure of the air taken from the outside is 100 kPa and the suction flow rate is 2.2 m3/s. According to this, a) What is the amount of moisture transferred to the air in the power plant? kg/h b) What is the thermal power transferred to the air in the power plant? is kW. NOTE: The total enthalpy of the air-water vapor mixture, with the mass of air ma and the mass of water vapor mv It is calculated by the relation h=ma1.005 T + mv(2501+1.82 T) (kJ/kg-dry_air). Tip: Calculate the masses of dry air and water vapor separately.

Question
At 0°C, 60% relative humidity, the air entering with 2.2 m3/s comes out with 30°C, 50% relative humidity. In this air handling unit, the air at 10°C temperature and 60% relative humidity from the outside is blown inside at 30°C temperature and 50% relative humidity, after heating and humidification processes. The total pressure of the air taken from the outside is 100 kPa and the suction flow rate is 2.2 m3/s. According to this,
a) What is the amount of moisture transferred to the air in the power plant?
kg/h
b) What is the thermal power transferred to the air in the power plant?
is kW.
NOTE: The total enthalpy of the air-water vapor mixture, with the mass of air ma and the mass of water vapor mv
It is calculated by the relation h=ma1.005 T + mv(2501+1.82 T) (kJ/kg-dry_air).
Tip: Calculate the masses of dry air and water vapor separately.
