Newton's Law of Viscosity

Newton's Law of Viscosity is a fundamental law that describes the behavior of fluids. It is also known as the law of viscosity or the Newtonian fluid law. This law states that the shear stress of a fluid is directly proportional to the rate of angular distortion of the fluid.

Shear Stress and Rate of Angular Distortion

Shear stress is a measure of the force per unit area that is required to cause a fluid to flow. Rate of angular distortion refers to the rate at which a fluid is deformed when it is subjected to shear stress. The greater the shear stress, the greater the rate of angular distortion.

Relationship between Shear Stress and Rate of Angular Distortion

According to Newton's Law of Viscosity, the relationship between shear stress and the rate of angular distortion is linear. This means that if the shear stress is doubled, the rate of angular distortion will also be doubled. Mathematically, this relationship can be expressed as:

Shear stress = viscosity x rate of angular distortion

where viscosity is a measure of the resistance of a fluid to flow. It is a constant that depends on the nature of the fluid and the temperature at which it is flowing.

Conclusion

In conclusion, Newton's Law of Viscosity is an important law that describes the behavior of fluids. It states that the shear stress of a fluid is directly proportional to the rate of angular distortion of the fluid. This law is applicable to Newtonian fluids, which are fluids that exhibit a linear relationship between shear stress and rate of angular distortion.
