  1. I'm working on designing a new pump station and in my analysis I ran across a burning question. In textbooks, pipe, and pump manufacturers literature they provide minor loss coefficients, K, for common fittings. Where do the K numbers come from in the tables? I ask because I want to know what the K values are for a 22.5 and 11.25 bend and a plug valve. How would I go about getting the K value for reducers? On the projects I'm working on I have a 12"x8" reducer and 8"x6" reducer and don't know what the K value is so that I can get the equivalent length. I know in the future I will run across this again as I select different size reducers. A colleague I work with uses slightly different method, L/D. Those values are different than what you see with K values. Even with that method I still don't have all the values I need. I have values for 90 and 45 degree bends not 22.5 or 11.25. L/D tables we have do not cover reducers either. Have any of you created a spreadsheet where you calculated your own K or L/D tables? TIA.
  2. I'm working on designing a new well and elevated storage tank for a water distribution system. Our client is requesting to use chlorine gas instead of sodium hypochlorite. They also have requested the addition of fluoride.Are there any good reference materials or books that could help walk me through the design? Google didn't yield many results. I found a few references to AWWA A100 and Ten States Standards. I'm not opposed to buying them if they can provide the info I need. Unfortunately I can't read the AWWA standard without purchasing. TIA.
  3. Has anyone tried this kind of spam? Asking for a friend.
  4. Another way you might see something like this is K factors. They're used to calculate frictional headloss with fittings. Sent from my Pixel 2 using Tapatalk

  6. Congrats on passing. There is really no secret on how to pass. Study smart, put the time in, work every problem you can get your hands on, and go take the exam. Sent from my XT1254 using Tapatalk
  7. If we log in, download the manual, do we get a new NCEES pencil? Sent from my XT1254 using Tapatalk
  8. I went down a similar path as well. In the organization I work for you can have a Ph.D in every discipline in engineering and still be a project engineer. The only two ways to advance is get your PE license and start applying for those PM jobs (higher paid position) or get your MBA and go to another department. The options are very limited in our organization. There is a third option where you leave the organization as a whole. Several of my colleagues have left in recent months for higher paying positions in the PM role. Sent from my XT1254 using Tapatalk

    Failed Scores

    Does the SofPE still offer the free repeat? Honestly if you have taken their class, failed the exam, and eligible for free repeat jump on that opportunity. Take the summer off and spend time with your family and hit the books again late August. Be sure to take breaks when you're tired and don't forget about your family. I carved out time for my family the second time around and when I got tired I closed my books. I think the breaks and family time helped me stay fresh, energized, and I studied smarter not harder. Don't be afraid to put the exam off until the next April so that you can be well prepared and only have to take the exam one more time instead of multiple times. Be sure to change your study habits, take every practice exam you can, go through as many study guides as you can, and you will get it next time. Don't worry about the cut score. Trying to figure it out is worse than trying to get a donkey to do calculus. Sent from my XT1254 using Tapatalk
  11. I'm gonna have to agree with smahurin. It doesn't matter but stick to your strengths. I chose construction because that's the field I work in. I will say this. No matter what you choose, stick too it and study 300 plus hours. I would also recommend EET course. They are the best, by far. Sent from my VS985 4G using Tapatalk ^This. One thing I looked at was taking the path of least resistance and trying to pick the easiest topic. Don't do that because it's a waste of time. No matter which topic you choose it will be equally difficult as the other topics. I went with Water Resources-Env. That's the bulk of my experience and I learned a lot while studying. Just like college you will get out of it what you put into it. Take a good prep class like the EET, Testmasters, or School of PE (that's what I took). Sent from my XT1254 using Tapatalk
  12. This largely depends on you, type of work you do, and your interests. Which topic is your favorite? Sent from my XT1254 using Tapatalk
