水滴 Drop (liquid)

(重定向自Droplet)
水滴

Esquema de un chorro de líquido en proceso de separarse en gotas.
Gotas de agua sobre la hoja de un árbol.

水滴,是小量的水体,能以任何形态出现。

一支简单的垂直管状物体,慢慢流动液体到末端,便形成最容易出现的水滴。当气态水份遇上冰冷的物体表面,冷凝作用便会发生,过度冷却水蒸气,雾化成水滴,结露的现象也是由于冷凝作用的关系。

数学上,垂直管状物体末端水滴的最大可承受重量可以此计算:

mg = 3 \pi a \lambda \cos \alpha

mg ,又即 W ,为水滴的重量; π 为圆周率; a 为管口半径; λ 为液体的表面张力; α 为接触角度(液面与刚体接触点的延伸切线与刚体平面之间的角度)。这个关系是简单地量度表面张力的基础,常用于石油工业。

此外,由于水和空气的折射率,光线折射和反射在雨珠表面,导致彩虹的形成。

The shapes of raindrops, depending on their sizes.

A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop. Drops may also be formed by the condensation of a vapor or by atomization of a larger mass of liquid.
