Answer 1

Answer:

Mechanical analysis is the determination of the size range of particles present in a soil, expressed as a percentage of the total dry weight. There are two methods generally used to find the particle-size distribution of soil: (1) sieve analysis - for particle sizes larger than 0.075 mm in diameter, and (2) hydrometer analysis - for particle sizes smaller than 0.075 mm in diameter.
