The Best What Is The Capillary Action Of Water 2023. As a power source, capillary pressure is one of the most popular microfluidic driving mechanisms. The rise of water in a thin tube inserted in water is caused by forces of attraction between the molecules of water and the glass walls and among the molecules of water themselves.

This movement does not require the force of gravity to occur. We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? Capillary action is responsible for moving groundwater from wet areas of the soil to dry areas.
