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...

Problem 4. In class we introduced the concept of a Newtonian fluid. A Newtonian Fluid is one in which the stress and strain rate relationship is linear and related by the fluid viscosity. Answer the following equations about Newtonian and Non-Newtonian fluid models. a) With a Newtonian Model, indicate what the shear forces are on the x-face of a fluid element. b) With a Newtonian Incompressible Model, indicate what the normal force is on the x-face of a fluid element—show...

1. Some non-Newtonian fluids behave as a Bingham plastic for which shear stress can be expressed as + For laminar flow of a Bingham plastic in a horizontal pipe of radius R, the velocity profile is given as 4wr -R)+ (r-R), where AP/L is the constant pressure drop along the pipe per unit length, is the dynamic viscosity,r is the radial distance from the centerline, and is the yield stress of Bingham plastic. Develop a relation for (a) the shear...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
