Introduction to Pipe Flow: Summary
Key points from this module:
- The mechanical energy equation includes head loss which accounts for friction in the flow.
- Major head losses consist of straight pipe while the minor losses take into account changes in the pipe, including bends and turns as well as valves, pumps, etc.
- Friction factors can be determined from the Moody chart.
- Energy from pumps and turbines must be included in the energy equation if they are part of a pipe system.
From studying this module, you should now be able to:
- Use the Moody chart to find the friction factor.
- Simplify the mechanical energy equation.
- Explain how friction affects pipe flow.
- Calculate major and minor head loss for both laminar and turbulent flow.
