Flexible wall permeability tests are usually performed using backpressure. These factors are taken into account during this experiment when the water flow is steady. The flowing fluid passes through the soil and enters the soil sufficiently to be present in the waste liquid at total density. This permeability test can be done from 0% to 100%
