AIRCONDITIONING AND VENTILATION SYSTEMS
For Questions 5 to 8 Saturated ambient air with a db-temperature of 5°C and a mass flow rate of 0.9 kg/s is divided into two streams. One stream passes through a heating section and leaves it with a relative humidity of 25%. The conditions of the other stream that bypasses the heater remains unchanged. The two streams are then mixed to produce the supply air stream at 24°C. The pressure is constant at 101.3 kPa. Question 5 Determine the partial pressure of water vapor of the heated air in kPa. Round your answer to 4 decimal places. Add your answer Question 6 The heat input by the heating coil in kW. Round your answer to 2 decimal places. Add your answer
Question 7 The mass flow of air through the bypass section in kg/s. Round your answer to 4 decimal places. Add your answer Question 8 Plot of the process in a psychrometric chart (use the ASHRAE Psychrometric Chart, and insert your answer as a JPG/PNG/PDF attachment file). Use the editor to format your answer
