Capillary Rise Calculator
A precise tool.
What is the Capillary Rise Calculator & How does it work?
Capillary rise is the phenomenon where a liquid column rises in a narrow tube against an external force like gravity. This occurs due to the cohesive and adhesive forces between the liquid molecules and the tube material.
h = frac{2gamma cos(theta)}{rho g r}
h = height of capillary rise, gamma = surface tension, theta = contact angle, rho = fluid density, g = acceleration due to gravity, r = tube radius.
The formula accounts for the balance between the surface tension force pulling the liquid up and the gravitational force pulling it down. The height of rise depends on the properties of the liquid, the material of the tube, and the geometry of the system.

Frequently Asked Questions
What is capillary rise?
Capillary rise is the phenomenon where a liquid column rises in a narrow tube due to cohesive and adhesive forces between the liquid and the tube material.
How do I calculate the height of capillary rise?
Use the formula h = (2Ξ³cos(ΞΈ)) / (Οgr), where Ξ³ is surface tension, ΞΈ is contact angle, Ο is fluid density, g is acceleration due to gravity, and r is tube radius.
What factors affect capillary rise?
Capillary rise is affected by surface tension, contact angle between the liquid and the tube, fluid density, gravitational force, and the radius of the tube.
Can you explain the role of surface tension in capillary rise?
Surface tension creates an upward force that pulls the liquid column up the tube against gravity.
What is the significance of the contact angle in capillary rise?
The contact angle determines how much the liquid wets the surface, influencing how high it can rise in the tube.
How does the radius of the tube affect capillary rise?
A smaller tube radius results in a higher capillary rise due to increased surface area per volume of liquid.
