  Drop (liquid) - Wikipedia, the free encyclopedia
The simplest way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter.
Drops may also be formed by the condensation of a supercooled vapor or by atomization of a larger mass of liquid.
where λ is the surface tension of the liquid and α is the angle of contact with the tube.

 Session FC - Drops.
Nonturbulent annular liquid wall jets in still air at normal temperature and pressure were studied, with a trip wire initiating growth of a turbulent boundary layer along the wall.
Liquid from the lower liquid phase is entrained and then dispersed by gas bubbles passing from the lower to the upper liquid phase.
Liquids motions are modeled using the inviscid, well tested, Lee model and the electric potential is obtained by solving Laplace's equation together with the appropriate boundary conditions.

 Liquid Drop Model of Nucleus
A liquid drop model of the nucleus would take into account the fact that the forces on the nucleons on the surface is different from those on nucleons on the interior where they are completely surrounded by other attracting nucleons.
The volume of the liquid drop is proportional to the mass number A, and the surface would then be proportional to the two-thirds power of A. The first step toward a liquid drop model of the nucleus would then be to postulate a volume term and a surface term in the form:
In the liquid drop model, this is included by using the even-odd nucleus as a reference and adding a correction term which is positive for even-even nuclei and negative for odd-odd nuclei.

 BBC NEWS | Science/Nature | Liquid drop takes big nano step
Edinburgh scientists have made a small blob of liquid move across a surface by shining a light in front of it.
The trick is in tiny "machines" about a millionth of a millimetre in size that coat the surface and propel the drop.
But when these structures are stimulated by ultra-violet light, a chemical reaction takes place and the rings all go to one end, changing the nature of the surface under the blob from a repulsive one to an attractive one.

 Bohr on the Liquid Drop Model of Fission   (Site not responding. Last check: 2007-10-10)
Due to the extreme importance of this discovery, I should be glad to add a few comments on the mechanism of the fission process from the point of view of the general ideas, developed in recent years, to account for the main features of the nuclear reactions hitherto observed.
In the case of ordinary reactions, in which the disintegration consists in the scope of a single particle, this conversion means the concentration of a large part of the energy on some particle at the surface of the nucleus, and resembles therefore the evaporation of a molecule from a liquid drop.
In the case of disintegrations comparable to the division of such a drop into two droplets, it is evidently necessary, however, that the quasi-thermal distribution of energy be largely converted into some special mode of vibration of the compound nucleus involving a considerable deformation of the nuclear surface.

In this model, the aggregate of nucleons has the same properties of a liquid drop, such as surface tension, cohesion, and deformation.
In this stage the substance is a liquid crystal.

 The Pitch Drop Experiment   (Site not responding. Last check: 2007-10-10)
Three years were allowed for the pitch to settle, and in 1930 the sealed stem was cut.
From that date on the pitch has slowly dripped out of the funnel - so slowly that now, 72 years later, the eighth drop is only just about to fall.
The experiment was set up as a demonstration and is not kept under special environmental conditions (it is actually kept in a display cabinet in the foyer of the Department), so the rate of flow of the pitch varies with seasonal changes in temperature.

Due to this the authors considered the cross flow in cylinder-array geometry, which is very similar to that of the pin-post, to examine the pressure drop correlation with liquid metals over pin fins.
Study lead to two major variables to influence the pressure drop: fluid properties, viscosity and density, and the relative length of the posts.
Correlation of the pressure drop between long and short posts and the prediction of the pressure drop of liquid metal in the pin-post mirror and comparison with an existing experiment are addressed.

 A drop of liquid
The structure and thermodynamic properties of the interface between a drop of liquid and its vapour have long been matters of controversy.
The system can be described in terms of its macroscopic thermodynamic properties, in terms of local thermodynamic properties or in the language of statistical mechanics.
It is shown that the second of these routes leads to difficulties but that there is good evidence that the first and third are concordant, at least as far as the term in R
