What does CWH mean in UNCLASSIFIED
Capillary Water Height (CWH) refers to the height to which water rises in a narrow tube or porous material due to capillary action. Capillary action is the ability of a liquid to flow against gravity through narrow spaces without the assistance of external forces.

Essential Questions and Answers on Capillary Water Height in "MISCELLANEOUS»UNFILED"
What is Capillary Water Height (CWH)?
How does CWH occur?
CWH occurs when water molecules interact with the walls of a narrow tube or porous material. The adhesive force between the water molecules and the tube walls is stronger than the cohesive force between the water molecules themselves. This causes the water to rise up the tube or through the pores against gravity.
What factors affect CWH?
Factors that affect CWH include:
- Tube diameter or pore size: Smaller diameters or pore sizes lead to higher CWH.
- Liquid surface tension: Liquids with higher surface tension, such as water, exhibit greater CWH.
- Liquid density: Lighter liquids have lower CWH.
- Gravity: Stronger gravitational forces reduce CWH.
What is the significance of CWH?
CWH has numerous applications, including:
- Soil science: Determining soil moisture content and water availability for plants.
- Paper industry: Controlling paper quality and ink absorption.
- Biological systems: Facilitating water transport in plants and animals.
- Chemical engineering: Separating liquids with different densities.
How can CWH be measured?
CWH can be measured using various methods, such as:
- Capillary tube method: Inserting a narrow tube into the liquid and measuring the height of the water column.
- Soil tensiometer: Measuring soil moisture content indirectly by measuring the tension in the water held in soil pores.
- Neutron probe: Using radioactive isotopes to detect water content in soil and measure CWH.
