Calculation of Seepage Velocity using Constant Head Permeability Test
Given:
Coefficient of permeability (k) = 0.1 cm/s
Specific gravity (G) = 2.65
Hydraulic gradient (i) = 2.5
Saturated water content (w) = 20%
Formula used:
Seepage velocity (v) = (k/i) * (Gw/γ)
where γ = unit weight of water = 9.81 kN/m³
Calculation:
Unit weight of water (γ) = 9.81 kN/m³
From the given data, we can calculate the water content (θ) as:
θ = w/(1 + w) = 0.2/(1 + 0.2) = 0.1667
Substituting the given values in the formula, we get:
v = (0.1/2.5) * (2.65 * 0.1667/9.81)
v = 0.72 cm/s (rounded off to two decimal places)
Therefore, the seepage velocity through the soil specimen is 0.72 cm/s.
Explanation:
The constant head permeability test is a laboratory test used to determine the coefficient of permeability of a soil specimen. This test involves applying a constant head of water to one end of the soil specimen and measuring the rate of flow of water through the specimen. The hydraulic gradient is the ratio of the difference in hydraulic head between the two ends of the specimen to the length of the specimen.
The seepage velocity is the rate of flow of water through the soil specimen per unit area. It depends on the coefficient of permeability, hydraulic gradient, specific gravity, and water content of the soil. The formula for calculating seepage velocity takes into account all these parameters.
In this question, we are given the coefficient of permeability, hydraulic gradient, specific gravity, and saturated water content of the soil specimen. By using the formula for seepage velocity, we can calculate the rate of flow of water through the soil specimen.
