well i would put about 5 gallons of soil in there, maybe a tiny bit less so it does not overflow.
The answer depends on the thickness of the covering layer. That, in turn will depend on what the soil is for: lawn will require less depth than flower beds.
lines that all the points on it have the same head pressure and eqipotential lines are always prependicular to the stream lines .
It depends on the density of the soil. If the soil is compacted or stepped on or moist of dry the amount of soil in 1m x 1m x 1m is going to vary. The density of loose soil is about 1200 kg per m3
750 square units of soil.
The uniformity coefficient and the coefficient of curvature tells us the soil gradient of each soil. The gradient is simply the classification of soils and gravels.
fertile soil and water.
Coefficient of consolidation (Cv) is a measure of time it takes for a soil to consolidate during the lab test.
it is a soil constant (coefficient of sub grade reaction)
less fertile, less quality,less productive
The coefficient of friction between soil and plastic pipes typically ranges from 0.2 to 0.6, depending on factors such as soil type, moisture content, and pipe material. It is important to consider these variations when designing pipe installation to ensure stability and avoid slippage.
The static coefficient of friction between concrete and soil typically ranges from 0.6 to 1.0, while the dynamic coefficient of friction is usually slightly lower, ranging from 0.5 to 0.8. These values can vary based on factors such as the roughness of the surfaces and the presence of any contaminants like water or debris.
less qulity of soil
rocky soil has less nutrients than regular soil.
cykieadriess soil
Any soil contain more or less sodium chloride.
