How much of a cold air stream at 18°C, 80% relative humidity should be mixed with 5.8 kg da/s of a warm air stream at 35°C, 60% relative humidity to obtain mixed air at 26°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.
