Question 7 6 pts How much of a cold air stream at 18°C, 80% relative humidity should be mixed with 3 kg da/s of a warm air stream at 35°C, 60% relative humidity to obtain mixed air at 27°C? Express your answer in kg da/s. Assume the mixing process is adiabatic and at standard atmospheric pressure. In your written solution, draw the process in the psychrometric chart. Question 8 6 pts Moist air undergoes a cooling and dehumidification process at a pressure of 101.325 kPa from an initial state 30°C db and 70% relative humidity to a final state at 20°C and 50% relative humidity. If the mass flow rate of the air at the initial state is 23.5 kg da/s, how much is the decrease in the water content of the air? Express your answer in kg/s. In your written solution, draw the process in the psychrometric chart, show the initial and final states and the values obtained from the chart.
