Discuss the below:
Q: Cranberries are harvested by flooding the bogs in which they are grown and raking them into troughs for transport. At the processing plant, the surface moisture on the berries is removed as they roll over a fine screen through which warm air is blown. The berries have an average diameter of 15 mm, and the thickness of the water layer is 0.2 mm.
If the velocity and temperature of the heated air are 2 m/ and 30°C, respectively, estimate the time required to dry the berries. Assume that the water film on the berries is also at 30°C.
