Capillary rise refers to the phenomenon in which a liquid rises or falls in a narrow tube due to surface tension. This occurs because of the adhesive forces between the liquid and the surface of the tube, as well as the cohesive forces between the liquid molecules themselves. When the liquid’s adhesive forces to the […]

Viscosity is a measure of a fluid’s resistance to flow or deformation. It quantifies the internal friction within the fluid as its molecules move past one another. A higher viscosity indicates a thicker fluid that resists flow more, while a lower viscosity indicates a thinner fluid that flows more easily. Where: L = Length of
