Topic 1 - Drying Part 2

Question 1

what do you call the R vs free moisture content curve?

Answer 1

Drying-Rate Curve

Question 2

in the anatomy of drying rate curve, the movement of the drying process is from?

Answer 2

right to left

Question 2

at this point, there is insufficient water on the surface to maintain continuous film of water

Answer 2

critical free moisture content

Question 2

in this period, there is a steady rate of removal of water

Answer 2

constant drying period

Question 3

this period happens when the entire surface is completely dry

Answer 3

second falling rate period

Question 3

here, there is decrease in the rate of water removal

Answer 3

falling-rate curve
