The temperature of the air in a dryer is maintained constant by the use of steam coils within the dryer. The product enters the dryer at the rate of one metric ton per hour. The initial moisture content is 3 kg moisture per kg of dry solid and will be dried to moisture content of 0.10 kg moisture per kg of dry solid. Air enters the dryer with a humidity ratio of 0.016 kg moisture per kg of dry air and leaves with a relative humidity of 100% while the temperature remains constant at 60°C. If the total pressure of the air is 101.325 kPaa, determine the specific enthalpy at dryer outlet in kJ/kg
