Is mechanical analysis of soil texture determined by law? If so, which one?

✅Explanation:
Stokes' law plays a crucial role in many commonly used methods. This law describes the settling velocity of particles in a fluid medium based on their size, density, and viscosity of the fluid.

• Here's how Stokes' law applies to soil texture analysis:
-Hydrometer method
-Pipette method

• Other options and explanations:
-Darcy's law: This law describes the flow of fluid through porous media like soil. While it may be relevant to understanding water movement in soil, it's not directly involved in determining texture.
-Fourier's law: This law deals with heat transfer, not relevant to soil texture analysis.
-Bernoulli's law: This law describes fluid flow properties, not directly applicable to soil texture analysis.
