#### Calculating Diameter in Pipe Flow: Summary

The answers to the ConcepTests are given below and will open in a separate window.

##### Key points from this module:

- The diameter of a pipe cannot be solved algebraically for turbulent flow.
- Either a trial-and-error or root solving program must be used to solve.
- Both major and minor losses can be included in your calculations.

##### From studying this module, you should now be able to:

- Rewrite the important equations in terms of diameter.
- Solve for the friction factor using both trial-and-error and Excel.
- Use the friction factor and the simplified energy equation to calculate the diameter.
