Question

The shear stress developed in the flowing fluid is 12N/m2 . The specific gravity of the fluid is 0.6. The velocity of the fluid flow is 3m/s. Find the viscosity of the fluid?

​

Answer 1

Explanation:

Fluid with zero shear stress within it is known as static fluid. When ever fluid moves it undergoes continuous deformation due to shear (caused due to viscosity of the fluid). So when the fluid is in rest no shear stress develops and only normal stress exists. So static fluid has zero shear stress.
