Flow is also proportional to the difference in height of the water from when it begins flowing through the pipe to when it comes out of the pipe. Obviously, it is the difference in hydraulic head from the start of the pipe to the end of the pipe that is generating the pressure pushing the water through the pipe. Finally, flow is inversely proportional to the length of the pipe. The more sediment that the water has to flow through, the more it will be impeded. The greater the value of K, the higher will be the rate of flow of a fluid through a material.
Hydraulic conductivity is similar to permeability.
The difference is that permeability is a property that is specific to the sediment, while hydraulic conductivity describes the behavior of a specific fluid and a specific sediment. In lab today, we will experimentally determine the hydraulic conductivities of three different sediments using a simple version of Darcy's original experiment. The apparatus used to measure hydraulic conductivity is called a permeameter.
