propustný

Propustný is a Czech adjective that translates to "permeable" or "porous" in English. It describes a material or substance that allows fluids, such as water or gas, to pass through it. This property is significant in various scientific and engineering contexts.

In soil science, a propustný soil allows water to infiltrate and drain, which is crucial for plant growth and groundwater recharge. Soils with high permeability are typically sandy or gravelly, while clay-rich soils tend to be less propustný. In environmental science, permeability is a key factor in understanding groundwater contamination and the movement of pollutants.

In material science and engineering, propustný describes materials that can be penetrated by fluids. For example, a propustný membrane in a filtration system allows certain substances to pass through while blocking others. This principle is used in technologies like reverse osmosis and dialysis. Clothing can also be described as propustný if it allows air or moisture to pass through, contributing to breathability. The degree of permeability is often a desired characteristic, influencing the performance and application of various materials.
