How to fill out EXPERIMENT 10 PERMEABILITY (HYDRAULIC CONDUCTIVITY) TEST

1. Gather the necessary materials: soil sample, permeameter, water source, measuring cylinder, stopwatch, and soil gradation kit.
2. Prepare the soil sample by ensuring it's uniform and free of debris.
3. Place the soil sample in the permeameter and ensure all connections are secure.
4. Fill the permeameter with water, ensuring there are no air bubbles trapped in the soil.
5. Begin the water flow through the soil sample at a controlled rate.
6. Use the measuring cylinder to collect the amount of water that flows through the sample over a set period.
7. Record the time taken for water to flow through the soil sample.
8. Calculate the hydraulic conductivity using the collected data and relevant formulas.

What is the permeability coefficient K?

Soils high in clay have low K values, about 0.05 to 0.15, because they resistant to detachment.

What is the permeability hydraulic conductivity test?

The purpose of this test is to determine the permeability (hydraulic conductivity) of a sandy soil by the constant head test method. There are two general types of permeability test methods that are routinely performed in the laboratory: (1) the constant head test method, and (2) the falling head test method.

What is the permeability value K?

In fluid mechanics, materials science and Earth sciences, permeability (commonly symbolized as k) is a measure of the ability of a porous material (often, a rock or an unconsolidated material) to allow fluids to pass through it.

What is the K value for the falling head permeability test?

The constant head test method is used for cohesionless and more permeable soils (k>10-4 cm/s) and the falling head test is mainly used for cohesive or less permeable soils (k<10-4 cm/s).

What is the constant falling head permeability test?

The falling head method of determining permeability is used for soil with low discharge, whereas the constant head permeability test is used for coarse-grained soils with a reasonable discharge in a given time. For very fine-grained soil, capillarity permeability test is recommended.

How do you perform a permeability test?

In this test, water is forced, by a falling head pressure, through a soil specimen of known dimensions and the rate of flow is determined. This test is used to determine the drainage characteristics of relatively fine-grained soils and is usually performed on undisturbed samples.

What is the purpose of the permeability test?

Coefficient of permeability is used to assess drainage characteristics of soil, rate of consolidation and to predict rate of settlement of soil bed. The coefficient of permeability is generally determined by two procedures (i.e. Constant Head Method and Falling Head Method).
