    Generally, for measurement of infiltration on the field we use the Cylindrical Infiltrometer of diameter 30 cm and 60 cm. Basic infiltration rate for a different type of soil are as below: If the infiltration rate is 1-5 mm/hour that it is Clay. If the infiltration rate is 5-10 mm/hour that it is ClRead more

    3. If the infiltration rate is 10-20 mm/hour that it is Loam.
    4. If the infiltration rate is 20-30 mm/hour that it is Sandy Loam.
    5. If the infiltration rate is greater than 30 mm/hour that it is Sand.

    As correctly stated that Fluid is defined as a substance which continuously deforms under applied shear force. Even though only after exceeding a certain shear stress value rheopectic, thixotropic, and Bingham plastic start undergoing shear deformation, it is to note that after that stress value, these substances also deform continuously until the external shear force is removed. Hence, they can be categorized as fluids.

    However, in case of solids under any amount of shear force, they undergo a fixed deformation and do not undergo continuous deformation.
