Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Blue and yellow streams of paint (each with a density of 1.6 slugs/ft³ and a viscosity 1500 times greater than water) enter a pipe with an average velocity of 9 ft/s as shown in the figure below. Would you expect the paint to exit the pipe as green paint or separate streams of blue and yellow paint? Explain. Repeat the problem if the paint were "thinned" so that it is only 10 times more viscous than water. Assume the density remains the same, and the temperature is 60°F. Classify the flow. Splitter Laminar Yellow Blue Laminar flow has mixing only by molecular diffusion. Turbulent flow has mixing due to large scale fluctuations. Reynolds number is a measure of whether flow is laminar or turbulent. Classification of viscous flow as laminar or turbulent dictates how the flow is analyzed. What is the Reynolds number for the flow with a viscosity 1500 times that of water? Re= 2 in. What is the entrance length for this Reynolds number? le= ft Green? 25 ft
