Question 4 A continuous countercurrent dryer is being used to dry 453.6kg dry solid/ h containing 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, Heating air enters at 93.3C, having a humidity of 0.010kgH2O/kg dry air, and is to leave at 37.8C. Calculate the air flow rate and the outlet humidity. Given: Heat capacity of air =1.00kJ/kgK and Heat capacity of water vapor =1.88kJ/kgK
