Another way to think about this that helped me clearly see the problem solving process is by setting it up as a mass balance. You have a mass loading rate in of n * x where n is the number of people and x is the mass of BOD produced by each person. The mass exit rate is Q * BODavg. Therefore, n * x = Q * BODavg. You can also do the same with a flow balance, n * Qavg = Q. By solving these two equations for Qavg through substitution of n, you get that Qavg = BODavg/x. Then you just have to apply a few unit conversions and you have your answer.

Hi! Please provide the page number where the loading equation is in the FE 10.2 book? I see some equations for loading in the "activated sludge" section, but it´s not the same one you´re using here

Very nice but the stick figure you drew should be drawn sitting down on a potty. 🤣

🤣🤣 I was honestly thinking about it after I finished the video! I was like "that would've been a much better representation of the situation we have". Well, it looks like I need to create another one of these potty questions!

@@directhubfeexam I'm starting my studies for the PE environmental and a lot of the FE stuff you've put out will be useful still. Do have any other tips? I got the ppi books and ncees practice exam as study materials and taking school of pe review. But I see some similarities which is comforting and some stuff I've never seen before , thumbing through the books.

@@dand7056 Morning Dan! That's awesome! Are you planning to take strictly the PE Environmental or the Civil Water Resources and Environmental Engineering? They are both extremely similar. Specifically, when it comes to how they're both related in the area of Water and Wastewater. The biggest difference I see is how the Environmental PE is more focused on air quality and environmental standards. So expect to get conceptual in those areas like environmental law, EPA quality standards, etc, etc, etc. I recommend making lots of flashcards for these! Everything you learned for the FE Environmental is crucial to knowing for the PE Environmental. In fact, expect that first section to feel almost identical! So make best use of whatever you can find on my channel and other channels as well. It sounds like you have more than enough study resources. For me, I think the less the better (so long as the quality is there). Don't overwhelm yourself with too many resources. Take each section one at a time and do the deliberate where you're reading over the theory and concept since that's often tested on these exams. Sorry Dan, that's all I can think of for the PE Environmental. It's a fun topic! I'm sure you'll find it satisfying!

@@directhubfeexam I'm doing the PE environmental. I know a bit about site remediation where the Civil I would need to learn more statics and transportation. Plus my degree is in Environmental so I'm staying in my lane. Transportation pun. You are right too many books will overwhelm you. With over 500 problems to complete I think that is more than enough plus all the school of PE notes problems and flashcards I have my work cut out for me. I'm planning to put in 5 to 6 months of study and take the test. Sound about right? Also did you ever take your PE?
