What is the conversion factor for hydraulic conductivity units?

In summary, hydraulic conductivity is a measure of how easily water can flow through a material and is important for understanding groundwater movement and potential contamination. The most commonly used units for hydraulic conductivity are cm/s and ft/d, but other units may also be used. Conversions between different units can be done by multiplying or dividing by certain factors. The hydraulic conductivity of a material depends on its properties, with materials like sand and gravel having higher conductivity compared to clay and silt. In the field, hydraulic conductivity can be measured through methods such as pump tests, slug tests, and infiltration tests, as well as indirect methods like electrical resistivity or ground penetrating radar.

Hi I am new to the forum,

I am using darcy's equation to model a tumor - tissue medium.

In the literature I found that K - Hydraulic conductivity is given by cm^2/(mmHg.s)
But in comsol it's given by (m/s)

Is there another term involved in this?

Related to What is the conversion factor for hydraulic conductivity units?

1. What is hydraulic conductivity and why is it important?

Hydraulic conductivity is a measure of how easily water can flow through a material, such as soil or rock. It is important because it helps us understand the movement of groundwater and the potential for contamination or water supply in a particular area.

2. What are the units of hydraulic conductivity?

The most commonly used units for hydraulic conductivity are centimeters per second (cm/s) in the metric system and feet per day (ft/d) in the imperial system. Other units such as meters per day (m/d) or millimeters per hour (mm/hr) may also be used depending on the context.

3. How do you convert between different units of hydraulic conductivity?

To convert from cm/s to ft/d, multiply by 86400 (the number of seconds in a day) and divide by 30.48 (the number of centimeters in a foot). To convert from ft/d to cm/s, multiply by 30.48 and divide by 86400. It is important to double check your conversions and use the appropriate units for your calculations.

4. How does hydraulic conductivity vary between different materials?

The hydraulic conductivity of a material depends on its properties, such as porosity and permeability. Generally, materials with larger pore spaces and connected pathways, such as sand and gravel, have higher hydraulic conductivity compared to materials with smaller pore spaces, such as clay and silt.

5. How is hydraulic conductivity measured in the field?

There are several methods for measuring hydraulic conductivity in the field, including pump tests, slug tests, and infiltration tests. These methods involve measuring the rate of water flow through a material under certain conditions, such as a constant head or constant volume. Other indirect methods, such as using electrical resistivity or ground penetrating radar, can also be used to estimate hydraulic conductivity.
