1. Wet solids pass through a continuous dryer. Hot dry air enters the dryer at a rate of 400 kg/min and mixes with the water that evaporates from the solids. Humid air leaves the dryer at 50°C containing 2.44 wt% water vapor and passes through a condenser in which it is cooled to 10°C. The pressure is constant at 1 atm throughout the system. a. At what rate (kg/min) is water evaporating in the dryer? b. Use the psychrometric chart...
(10 pts) Six-thousand cubic feet per minutes (C.F.M.) of atmospheric air at 28°C (dry bulb) having a wet bulb temperature of 23°C is to be cooled in an air conditioning system. The air conditioning system lowers the dry bulb temperature of the air to 20° C. Cooling with dehumidification is accomplished using chilled water loop. The chilled water enters the loop at 5°C at a rate of 280 kg/min and experience a 5°C temperature increase. The atmospheric pressure is 1...
