  1. Congrats all :)!!!
  2. Hey guys, I was solving an atmospheric dispersion question and was a little confused on something. In the problem, stability class is C and effective stack height H was given as well. Since the downwind distance X was not given, they used the formula H/square root of 2 to find the vertical dispersion parameter (z). Then they used the graph on Page 67 of the NCEES Handbook to find downwind distance X using the Class C and vertical dispersion parameter. Here is my confusion: On Page 52 of the NCEES Handbook, it says this equation is for Neutral atmospheric conditions. Isn't that Class D then? Can this equation be used for other Stability Classes? I hope someone can clear this out for me. Thanks so much in advance
  3. Congrats @waternerd @jtimothythompson!!!
  4. @jtimothythompsonfingers crossed that you pass Good luck! Can you tell us how you prepared for the exam?
  5. @environ-profCongrats! Seems like the CBT exam is doable since everyone seems to be doing well Makes me feel a bit better lol Just wondering if they take away your old dry-erase notepad, can you request it back to check your work? I wouldn't feel comfortable returning the dry-erase pad knowing that I want to re-check my work at some point lol
  6. Thanks @Kara_ENGR. And wow 10 months!? Mine took 4 months and even then I was so anxious :/
  7. @Kara_ENGRI'm going to be taking the exam in NY as well - just wondering when you scheduled your exam through NCEES, did you have to pay $375? Because I thought the fee that we already paid to the NYS board ($377) would cover for the first time we take the exam. Please advise - thanks!
  8. Does anyone know a good source for studying Solid Waste Management? I have the introduction to Environmental Engineering textbook which briefly goes through it but there were barely any problems to work out (or the problems barely aligned with the reference manual equations). Also, would I have to know how to calculate truck routes? I just don't feel super confident in this section due to the lack of resources.
  9. @Waterchild best of luck!!
  10. @GirlsCanDesignAWESOME!! Congrats!!! 🎉🎈✨
  11. I'd like to know this as well! lol I just tried searching on amazon & ebay for books but didn't find one. I know Chegg has textbook solutions so that might be an option.
  12. @MaryamWhere did you find them for that amount? I think it might be the older books, but trying check the ISBN number.
  13. Thank you both! @txjennah PE@GirlsCanDesign
  14. @waternerdThese are the two CBT Schneiter books on PPI that @GirlsCanDesignhad recommended to me (thanks again!) I'm definitely going to get the practice book with 500 problems. I'm still debating on the exam booklet with two exams (80 questions) though... I just hope it doesn't have the same questions as the practice book since it's the same author 😅
  15. Hey all I'm getting really hung up on what length (distance) to use in the hydraulic gradient equation. In the solution below, they use the "diagonal" distance between the wells. I would have just used 175 ft. The example from this link also used the "horizontal" distance Which one is the correct value to use?!
