Air with a dry-bulb temperature of 38 °C and a wet-bulb temperature of 27 °C is scrubbed with water to remove dust. Water temperature is maintained at 25 °C. The air leaving the scrubber is in equilibrium with water. It is then heated to 93 °C in an air preheater and admitted to an adiabatic rotary drier. The air leaves the drier at 49 °C. The material losses moisture at a rate of 0.05 kg of water per kg of product. The total product is 1000 kg/h. Determine the following (Use a psychrometric
