Answer: Option A
Solution
Answer: Option A
Solution:
The pipette method is a more accurate method of determination of soil texture.The pipette method consists in using a pipette to take a specific volume of a water suspension of soil. If solid particles suspended in a liquid are allowed to settle freely, then by stroke's equation, after a selected time interval, t, all the particles larger than the diameter, d, will have fallen below a level designated as M.
