This article explores viscosity terms and definitions, unraveling the intricacies of fluid behavior. Absolute Viscosity - The force required for a liquid to overcome its internal friction and commence ...

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 ...

Sound waves can measure viscosity on the fly. Though viscosity is the degree to which a fluid resists flow, it is more specifically a measure of a fluid's molecular friction. It can be a useful ...

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey ...

A fluid's viscosity, its resistance to flowing, is usually expressed as the ratio of its shear velocity of motion to rotational torque. It's difficult to measure because it's so dependent on ...
