A fluid in which resistance to deformation is independent of the shear stress, is known as
- A.Bingham plastic fluid
- B.Pseudo plastic fluid
- C.Dilatants fluid
- D.Newtonian fluid
Show answer
In such a fluid the shearing stress is directly proportional to the rate of shear, so the coefficient of viscosity, which measures the resistance to deformation, keeps the same value whatever the stress applied; water, air, petrol and thin oils behave in this way.
