Q650
Relation of De (diffusion coefficient) with moisture content (θ)
A.
De increase with increase in θ
B.
De decrease with increase in θ
C.
De increase with increase in θ upto saturation
AnswerD.
None of the above
Answer: Option C
Solution
Answer: Option C
Solution:
The diffusion coefficient (D) is the amount of a particular substance that diffuses across a unit area in 1 s under the influence of a gradient of one unit.Moisture content is determined by subtracting the dry weight from the initial weight, and the moisture content is then calculated as the amount of water divided by the dry weight or total weight.
The relation of De (diffusion coefficient) with moisture content (θ) is that De increase with the increase in θ up to saturation.
