Questions 1 to 4 In an air conditioning system, return air at 24°C dry-bulb temperature and 40% relative humidity is mixed with outdoor ambient air at 30°C dry-bulb temperature and 70% relative humidity. The dry air mass flow rate of outdoor air is 20% of the supply air mass flow rate to the space. The pressure is constant at 101.3 kPa.
Question 1 Calculate the dry-bulb temperature of the supply air in °C. Round your answer to 1 decimal place. Add your answer
Question 2 The humidity ratio of the supply air. Round your answer to 5 decimal places. Add your answer
Question 3 The enthalpy of supply air in kJ/kg. Round your answer to 2 decimal places. 10 Points 10 Points 10 Points
