Define shear stress as it applies to a moving fluid.
Shear stress as it applies to a moving fluid.
Explanation of Solution
Shear pressure is most ordinarily connected to solids. Shear powers acting extraneously to a surface of a strong body cause disfigurement. As opposed to solids that can oppose miss happening, fluids do not have this capacity, and stream under the activity of the power. At the point when the liquid is in movement, shear stresses are created because of the particles in the liquid moving in respect to each other.
For a liquid streaming in a pipe, liquid speed will be zero at the pipe divider. Speed will increase while moving towards the focal point of the pipe. Shear powers are regularly present on the grounds that adjoining layers of the liquid move with various speeds contrast with one another.
By thinking about the speed of this relative movement, shear rate,
