A drier is processing a solid containing 30% by weight moisture to a final product containing 5% moisture. Air at 80°C and 100 kPa with a molal humidity of 0.012 kmol H2O/kmol dry air is used as drying medium. It goes out of the drier at 40°C and 750 mmHg with a humidity of 0.065 kmol H2O/kg dry air. If the water evaporated in the drier is 30 kg/min, calculate: a) the kg of product per minute b) the volume of the outgoing air in m³/min

Question
A drier is processing a solid containing 30% by weight moisture to a final product containing 5% moisture. Air at 80°C and 100 kPa with a molal humidity of 0.012 kmol H20/kmol dry air is used as drying medium. It goes out of the drier at 40°C and 750 mmHg with a humidity of 0.065 kmol H2O/kg dry air. If the water evaporated in the drier is 30 kg/min, calculate: a) the kg of product per minute b) the volume of the outgoing air in m/min
