In order to increase the humidity of an air stream having a temperature of 55°C and humidity of 0.002 kg/kg, water is sprayed into it in the form of a fine mist; the mist droplets evaporate in the airstream. The water temperature is 20°C and the flow rate of the airstream is 10 kg/s (dry air). What fow rate of water would be required to bring the relative humidity to 50% and what would be the temperature of the resultant stream?
