conditioning processes. (10) b) One thousand cubic meters of moist air at 101 kPa and 220C

and with a dew point of 110C enters a process. The air leaves the process at 98 kPa with a dew point of

580C. How many kilograms of water vapor are added to each kilogram of wet air entering the process?

continuous drier. [6]

(b) In a laboratory test the dryin g of a solid material, the following relationship was obtained for the

falling rate period: dw/dt = -0.8(w - 0.031) where w is free moisture content, kg per kg of dry solid and

t is time in hours. Critical moisture content of the solid under prevailing conditions was found to be 1.4

kg per kg of dry solid. Determine the time required to dry the material from initial moisture content of

4kg per kg of dry solid to a final moisture content of 0.1 kg per kg of dry solid. [10]
