Question: 2 air enters an adiabatic drier at 6 ms through...

Question details

(2) Air enters an adiabatic drier at 6 m/s through a 2-m wet bulb temperatures. It is heated to 80°C before reaching the material to be dried and leaves the drier at 44°C and 80 per cent relative humidity. Thie material enters the drier with a moisture content of 24 per cent and leaves with a moisture content of 8 per cent. Determine (a) the mass of water removed per kg of dry air, (b) the volume flow rate of air entering the reheater, (c) the kg of water evaporated per second, (d) the mass flow rate of material leaving the drier and (e) the heat requirement of drier per kg of water evaporated diameter duct at 29°C dry bulb and 22°C
