A solid material containing 15% w is 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 0.1kg H20/ kg dry air and the mixed air to the drier of 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
Transcribed Image Text:A solid material containing 15% w is 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 0.1kg H20/ kg dry air
and the mixed air to the drier of 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.
