When the air temperature is below 0 ?C, the water at the surface
of a lake freezes to form a sheet of ice.
If the upper surface of an ice sheet 24.64cm thick is at
-10.58?C and the bottom surface is at 0 ?C, calculate the time it
will take to add 2.41mm to the thickness of this sheet.

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?
