AMONG the properties of liquids the viscosity is probably the one the investigation of which has suffered most from lack of any accepted theory, however crude and approximate, to guide it. A great ...

With an increase in temperature in a fluid, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. Viscosity typically decreases as temperature ...

Getting ketchup out of the bottle isn't always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated.

In a new study, scientists show that two fundamental physical constants govern how runny a liquid can be. Their equation relates the minimal value of elementary viscosity (the product of viscosity and ...

To understand viscosity, laminar flow must be understood. This is when a gas or fluid flowing over a surface results in the molecules next to the surface having zero speed. As the distance from the ...

Viscosity is a term used to describe the resistance of a liquid to flow. For most liquids, viscosity depends on temperature - these are Newtonian. For other liquids, Non-Newtonian, the viscosity ...

Pharmaceutical companies have increasingly focused on developing high-concentration protein therapeutics that enable patients to treat themselves at home by self injection. However, the formulation of ...
