Wet coal amounting to 10000 ton/day is dried in an air dryer .The wet coal feed enters with 12% by mass of water and exits with 2%.The hot air used to dry the wet coal is fed at 40°C dry‐bulb temperature ,and 16°C wet‐bulb temperature .The moist air exits the dryer with 30% Relatively Humidity at 30°C. Calculate the amount of dry air at m3/h at STP. Use psychrometic chart
