A stream of outdoor air is mixed with a stream of return air in an air-conditioning system that is operated at 101.325 kPa barometric pressure. The flow rate of outdoor air is 2.0 kg/s and its condition is 35°C DBT and 25°C WBT temperatures. The flow rate of return air is 3.0 kg/s and its condition is 24°C DBT and 50% RH. If the ambient pressure is 98 kPaa, determine the following: 1. Enthalpy of the mixture in kJ/kg 2. Humidity ratio 3. Dry bulb temperature of the mixture in °C

Question
A stream of outdoor air is mixed with a stream of return air in an air-conditioning system that is operated at 101.325 kPa barometric pressure. The flow rate of outdoor air is 2.0 kg/s and its condition is 35°C DBT and 25°C WBT temperatures. The flow rate of return air is 3.0 kg/s and its condition is 24°C DBT and 50% RH. If the ambient pressure is 98 kPaa, determine the following:
1. Enthalpy of the mixture in kJ/kg
2. Humidity ratio
3. Dry bulb temperature of the mixture in °C
