The capillary length will vary for different liquids and different conditions. Here is a picture of a water droplet on a lotus leaf. If the temperature is 20 o then = 2.71mm . The capillary length or capillary constant is a length scaling factor that relates gravity and surface tension.
The equation can be non-dimensionalised in terms of its characteristic length-scale, the capillary length: =, and characteristic pressure = =. For clean water at standard temperature and pressure , the capillary length is ~2 mm .
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.

Flow through the pores in an oil reservoir has capillary number values in the order of 10 −6, whereas flow of oil through an oil well drill pipe has a capillary number in the order of unity. [ 4 ] The capillary number plays a role in the dynamics of capillary flow ; in particular, it governs the dynamic contact angle of a flowing droplet at ...
The average length of time before a new union signs its first contract is 465 days, according to a Bloomberg Law analysis in 2022. Nearly 990 days have passed since Amazon workers in New York City ...
The Bond number can also be written as = (), where = / is the capillary length. A high value of the Eötvös or Bond number indicates that the system is relatively unaffected by surface tension effects; a low value (typically less than one) indicates that surface tension dominates. [ 7 ]
A French author and anatomist, Charles Estienne undertakes anatomical dissection on a massive scale. He publishes all of his findings in his book Dissection Des Parties Du Corps Humain, which translates to Dissection Of The Parts Of The Human Body. Estienne’s findings in regard to the clitoris are anatomically incorrect and fundamentally flawed.
