Hello and thank you for joining us for today's FE review topic on pumps. We will be covering a couple of example problems related to material similar to what might be found on the FE Exam. The first problem looks at sizing a pump to provide a minimum required system head while the second looks at sizing a pump based on pump and system curves. Thanks for watching!

In the FE reference handbook, there is an equation on pg. 297 called "circular pipe head loss equation" where Hf = [(4.73)(L) / (C^1.852)(D^4.87)] (Q^1.852). Can this equation be used here? My answer was [(4.73)(2000ft) / (120^1.852)(0.83^4.87)] (8^1.852) = 155.55 ft.

For the total head loss why can't we use the Darcy-Weisbach equation.

Thanks for the video. In the first question, I got S to be 0.0764. Same values for k, v C, and Rh, so my total pump head was 183 ft instead of 206 ft

Hello, Ryan, and thank you for your comment! After rechecking the calculation, I think you are correct that there’s a calculation error when calculating the hydraulic slope. I believe the error is in the calculation only and the formulas and concepts are still valid. I really appreciate you not only catching this error but also brining it to our attention. We hope you found the video otherwise helpful!
