In this segment, we introduce viscous flow in pipes, including Turbulent, Laminar, Transitional flows, Entrance Region, Fully-Developed Regions.

11:08 - Pressure Gradient in Entrance Region and Fully-Developed Flow

Module 11: Viscous Flow in Pipes
In Modules 5, 6, and 7, we applied the Reynold's Transport Equation to Conservation of Mass, Momentum, and Energy, respectively.

In Modules 8 and 9, we studied differential analysis of fluid flow, applied the fundamentals to obtain Conservation of Mass and Momentum equations, respectively

In Module 11, we will apply these basic principles to a specific and very important real-life application - the incompressible and compressible flow of viscous fluid in pipes and ducts. You can imagine the wide application space of this module to the mechanical engineering discipline. I would like to bring to your attention that this is the first module, where we discuss compressible flow, viscous flow, and Laminar, Transitional and Turbulent flow regimes.

Student Learning Outcomes
After completing this module, you should be able to:
1) identify and explain various characteristics of the flow in pipes
2) discuss the main characteristics of laminar and turbulent pipe flows and appreciate their differences
3) calculate losses in straight portions of the pipes (major losses), as well as those in various pipe system components (minor losses)
4) apply appropriate equations and principles to analyze a variety of pipe flow situations. This material is based upon work supported by the National Science Foundation under Grant No. 2019664.
