Physical aspects of pouring
– Parameters such as pouring speed, distance between containers, vibration, and heat transfer can affect the liquid being poured.
– Changes in the liquid may be desirable or undesirable depending on the context.
– Malaysian-style ‘teh tarik’ involves pouring brewed tea mixed with milk back and forth between containers to create foam and cool the tea.
– Industrial casting processes can create defects in the final cast part due to the pouring of molten metal.
– Automated pouring equipment has been developed for industrial settings to control variables and minimize danger.

Pouring is the act of tilting an open container which has liquid or bulk flowable solid inside of it, to cause the contents to flow out of the container under the influence of gravity. This may be done to move the contents to another container (such as pouring a shared drink from a bottle into individual cups), to coat a surface with the contents (as in pouring a syrup onto solid food, or the artistic technique of paint pouring), or simply to empty the original container.
