  1. Have you completely shut the valve? Steam is not linear (as I'm sure you know). I would shut the valve all the way and see if you get better control. If you do, treat the damper and valve as 1/3 (damper) and 2/3 valve to maintain a coil leaving temperature of 50 degF at all times. If the control guys ask what that means tell them to use ONE PID loop and control the damper from 0-33% and the valve from 33 - 100%. Sent from my SM-N950U1 using Tapatalk
  2. Do you have a coil discharge sensor installed? Sent from my SM-N950U1 using Tapatalk
  3. The steam valve is 100% closed or open? I'm assuming open with that type of Delta T Sent from my SM-N950U1 using Tapatalk
  4. Passed the FE at 44 and the PE @ 45. Makes me want to drink thinking about it... Sent from my SM-G935V using Tapatalk
  5. My degree is ME but I've spent my career on the HVAC Controls side of things so I decided to take the HVAC depth rather then the Controls exam because for one I didn't want to wait to take the exam in October of each year and I thought I had enough surface level knowledge of HVAC to pass the test. I should add that I also had been out of school for 22 years at that point as well. I did pass the HVAC using School of PE which helped tremendously. My point of telling the story is go with what you feel most comfortable with and Learn the subject and you will be fine. Mike Sent from my SM-G935V using Tapatalk
  6. I checked mine religiously until the email popped up. Then I sat there for like 5 minutes contemplating whether to open until I finally said "F" it! Luckily I was successful and walked around the office like a BOSS! Sent from my SM-G935V using Tapatalk
  7. My MERM IS at work so please forgive me for not having the page number available. But the graph is in the MERM (Reynolds Number to Coefficient of Drag). In order to calculate you need the Drag Force against the fluid, fluid velocity, face area of object to fluid and mass density of the fluid (for air at that temp). In order to use the graph you have to calculate the Reynolds Number and also remember you only care about surface area (facing fluid force) so when you have various sizes you need to break each up individually so that you can calculate Cd for each section.
  8. I took the SOPE for Mechanical HVAC and had the same issue you are having. What I found was that I needed to have read the material BEFORE the class so that I was prepared to follow the lecture and work the problems. My suggestion is to try to get ahead and do the problems before the class so that you can catch the key concepts. Good luck!
  9. My Grandmother (First Black RN for Riverside Hospitals in Columbus, O.) always said "No test is hard if you are prepared" Know and understand the material and you'll be fine. Nothing beats anxiety then answering a bunch of questions correctly and getting on a roll. Good luck!
  10. I agree with the allan. You should be fine. The new version has more HVAC information in it but that's pretty much it.
  11. Did you apply for disability waiver from NCEES? If your disability is documented they will make accommodations for it such as more time, splitting the rest up over several days etc... Don't be shy about asking for it if needed.
  12. Better hope it's a better speaker then they guy at the last Certificate ceremony. I did everything I could not to fall asleep.
