In a solid, shear stress is related to shear strain. In a fluid, shear stress is related to: The magnitude of the shear strain The slope of the shear strain The time rate of change of the shear strain The viscosity The Reynolds' number Flag this Question Question 21 pts Picture the flow of a fluid which has a non-zero viscosity in a pipe. Where is the velocity of this flow the greatest? At the wall fo the pipe Half...
дvх . (7) A Bingham plastic fluid has the following stress-strain rate relationship t = 600 + 0.1 For a Couette flow (slide 39) what would be the velocity profile if the shear ду stress applied at the top layer is 200 units? What would be the velocity profile if the applied shear stress at the top layer is 1000 units? Assume the height of the fluid is H. Simple Shear Flow F T=- A where t is shear stress...
2) (35 points) It is a common practice when examining a fluid's viscous behavior to plot the shear strain rate (velocity gradient) dv dy on the abscissa versus shear stress (t) on the ordinate. When a fluid has a straight-line behavior between these two variables it is called a Newtonian fluid, and the resulting relationship is where u is the fluid viscosity. Many common fluids follow this behavior such as water, milk, and oil. Fluids that do not behave in...
