Air enters a counter-flow drier at 70˚C dry bulb temperature and 20˚C dew point temperature. Air leaves the drier at 40˚C and 60% relative humidity. The initial moisture content of the product is 82% (wet basis). The amount of air moving through the drier is 2000kg of dry air per hour. The mass flow rate of the product is 10kg dry solid per hour. What is the final moisture content of the dried product in wet basis?
