Definition
Capillary tubing refers to the material used to create capillary tubes, which are narrow tubes with a small internal diameter. ๐งช This tubing facilitates capillary action, allowing liquids to flow without external forces. Unlike regular pipes, capillary tubing relies on surface tension and adhesion. Imagine it as a miniature plumbing system for liquids. Capillary tubing is commonly found in refrigeration systems and scientific instruments. The diameter is crucial for its proper functioning.
