  1. As the Computer Based Testing (CBT) is implemented for all Engineering PE exams starting from April 2020, I would like to initiate a thread to share the experience on Mechanical engineering HVAC & R and Thermal Fluid Systems (TFS) - PE exam as soon as candidates take the exam and share their experience. Below are some areas of concern, Note: Do not post and disclose any question or part of question here. This is just to share overall experience by not disclosing any details of the exam. 1. Overall difficulty level? 2. Question outside the NCEES reference manual? If yes diff
  2. Has any one here taken Dr. Tom's Classroom as prep for the PE? I enrolled in the fast track course and have currently completed weeks 1-4. I appreciate having the extra guidance and structure but I can't help but feel that the course is giving me a false sense of security. The assessment quiz questions and challenge problems don't seem to be all that difficult to me... is this because I'm well prepared or is the material too easy in comparison to the actual exam? He also assigns problems out of Six Minute Problems TF and the 2016 NCEES exam and I've been able to work through these without any
  3. Hello All, Does anyone know where I can download or buy past NCEES practice exams for the Thermal Fluids exam? I currently have the 2016 version by NCEES and I saw 2011 and 2008 version mentioned on this forum before. Thank you! and congrats to anyone that passed their exam and good luck to anyone that is going to be taking it in October.
  4. Condensed Problem statement: 40ft of 4in sch. 40 steel pipe containing five long radius 90deg. elbows + one gate valve + one sharp edge. V=16ft/s, f=0.019 Book Solution: K_entrance = 0.5 and all others included in the equivalent length as 40ft + 5(6.4ft) + 2.5ft = 65.5 and total head loss calculated as K*v^2/(2g) + f*(65.5)*v2/(2Dg) and answer = 16.7ft My method: K_entrance + K_all others = 0.5+5(0.6)+0.19 = 3.69 and total head loss = v^2/(2g)*(3.69+f*(40)/D) = 23ft I always thought the same answer is achieved whether we take K as a loss or included as an equivalent length, what
  5. Hello TFS test takers. Have some fun with this one. Difficulty level; I'd guess 2 on the scale from 1 to 5. SPOILER ALERT: Try to solve it first; then scroll down to see the replies.
