I wouldn't think so. None of that was covered in the prep class I took. I'm getting ready to make a run through on my Six Minute Solutions book so it might be in that but not sure. From what NCEES and the prep class I took is saying, you have to know how to calculate NPSHA, TDH, read a pump curve, and even plot a pump curve. One more thing, I would also cover EGL and HGL if you haven't already. The latter is something you probably already know how to do. One of my co-workers took the WR/Env exam a few years ago and said that there were several algae problems in the afternoon. If you have an environmental textbook like Davis & Cornwell or Metcalf & Eddy you should be fine. Hopefully this well help. Good luck!
