A solid material containing 15% w moisture is dried so that it contains 7% w H2O by blowing fresh air mixed with recycle air over the solid in the drier. The inlet fresh air has a humidity of 0.01 kg H2O/kg dry air. The air from the drier that is recycled has a humidity of 0.1 kg H2O/kg dry air and the mixed air to the drier 0.03 kg H2O/kg dry air. For a feed of 100 kg solid /hr fed to the drier, calculate (a) kg/hr of dry air in the fresh air (b) kg/hr of dry air in the recycle air c) kg/hr of dried product.

Question
A solid material containing 15% w moisture is dried so that it contains 7% w H2O by
blowing fresh air mixed with recycle air over the solid in the drier. The inlet fresh air has a
humidity of 0.01 kg H2O/kg dry air. The air from the drier that is recycled has a humidity of
0.1 kg H2O/kg dry air and the mixed air to the drier 0.03 kg H2O/kg dry air. For a feed of 100
kg solid /hr fed to the drier, calculate (a) kg/hr of dry air in the fresh air (b) kg/hr of dry air in
the recycle air c) kg/hr of dried product.
