Question

Difference between newtonian and non newtonian flow

Answer 1

in continuum mechanics a newtonian fluid is a fluid in which the viscous stresses arising from its flow at every point are linearly proportional to the local strain rate.newtonian fluids are the simplest mathematical model of fluids that account viscosity.
A non newtonian fluid is a fluid that dies not follow newtons law of viscosity ie constant viscosity independent of stress.most commonly the viscosity of non newtonian fluids is dependent on shear rate or shear rate history.....
