In the late 1910s and early 1920s a pair of scientists independently developed an equation that describes how a fluid rises in a capillary tube as a function of time. The formula—the Lucas-Washburn ...

Tube radial distribution chromatography (TRDC) is an innovative separation technique that exploits the spontaneous radial segregation of mixed solvent systems under laminar flow conditions in ...

As energy costs and regulatory demands for system efficiency increase, thermostatic expansion valves (TXVs) are replacing capillary tubes, particularly in residential air conditioning and heat pumps.
