Example 5.1 Heat Balance on a Dryer A continuous counter-current dryer

Example 5.1 Heat Balance on a Dryer A continuous counter-current dryer is being used to dry 453.6kg dry solid/ 0.04kg total moisture /kg dry solid to a value of 0.002kg total moisture /kg dry solid. The granular solid enters at 26.7C and is to be discharged at 62.8C. The dry solid has a heat capacity of 1.465kJ/kg.K, which is assumed and is constant. Heating air enters at 93.3C, having a humidity of 0.010kgHH2O/kg dry air, and is to leave at 37.8C. Calculate the air flow rate and the outlet humidity, assuming no heat losses in the dryer
