Humid air at 75°C, 1.1 bar and 30% relative humidity is fed into a process unit at a rate of 1000 m³/h. Determine: 1. The molar flow rates of water, dry air and oxygen entering the process unit 2. The molal humidity and absolute humidity of the air 3. The dew point Relative Humidity = Sr (hr) = P₁₂ (T) P₁
