Strategies for Measuring Viscosity, What’s excessive viscosity

There are a number of ingenious methods scientists and engineers decide a fluid’s viscosity, every suited to several types of fluids and measurement necessities. These strategies typically work by observing how a fluid resists a mechanical power or how shortly it flows underneath gravity or strain. It is a bit like testing a runner’s velocity or a fabric’s energy, however for liquids and gases.Listed here are some widespread approaches:

Kinematic viscosity, typically denoted by the Greek letter nu ($nu$), relates dynamic viscosity to the fluid’s density. It basically measures how simply a fluid flows underneath the affect of gravity. It is the ratio of dynamic viscosity to density.

The SI unit for kinematic viscosity is the sq. meter per second (m²/s).

Nonetheless, the generally used unit is the Stokes (St), named after Sir George Gabriel Stokes. One Stokes is the same as 0.0001 sq. meters per second (10⁻⁴ m²/s). A smaller and extra ceaselessly used unit is the centistokes (cSt), the place 1 cSt = 1 mm²/s = 10⁻⁶ m²/s.The connection between dynamic and kinematic viscosity is simple:
