What Is Newtonian Fluid

What Is Newtonian Fluid. The description of these fluids is as follows. These fluids have a linear relationship between viscosity and shear stress.

These fluids have a linear relationship between viscosity and shear stress. For newtonion fluids, the relationship between shear stress and shear rate is linear. Where stress is proportional to rate of strain, its higher powers and derivatives (basically everything other than newtonian fluid).

Why do we have to assume for Newtonian fluid when doing calculations

A newtonian fluid is an idealization. Where stress is proportional to rate of strain, its higher powers and derivatives (basically everything other than newtonian fluid). Under constant temperature and pressure conditions, the viscosity of a newtonian fluid is the constant of proportionality, or the ratio,. A newtonian fluid is any fluid that exhibits a viscosity that remains constant regardless of any external stress that is placed upon it, such as mixing or a sudden application.
