1. Different types of pump systems 2. Three important characteristics of a pump system: pressure, friction and flow 3. What is friction in a pump system 4. Energy and head in pump systems 5. Static head 6. Flow rate depends on elevation difference or static head 7. Flow rate depends on friction 8. How does a centrifugal pump produce pressure 9. What is total head 10 What is the relationship between head and total head 11. How to determine friction head 12. The performance or characteristic curve of the pump 13. How to select a centrifugal pump Examples of total head calculations - sizing a pump for a home owner application 14. Examples of common residential water systems 15.

Foreword This tutorial is intended for anyone that has an interest in centrifugal pumps. There is no math, just simple explanations of how pump systems work and how to select a centrifugal pump. For those who want to do detail calculations, some examples have been included in the appendices. This tutorial answers the following questions: What are the important
