  1. Ryan, You should be thinking about your next job, after this one. If you already know AutoCAD move to Revit. I look at the jobs I want to apply for now but they require proficiency in Revit. I only know AutoCAD. That leaves me in a disadvantage.... Advance your knowledge. Advance yourself.
  2. I have stuff for sale in the Yard Sale section. As far as the conversions, people have been using the 4th ed for a long time. I used it 3 years ago. 2nd ed. has 146 pages. (Copyrighted 1990) 4th ed. has 160 pages. (Copyrighted 2009) Individual pages could have expanded or corrected.... I think it is best to go with a newer version
  3. I just put up for sale my set of Ashrae Handbooks 2008-2011 in the "Yard Sale".
  4. I do. I have it for sale in the yard sale...
  5. I started using SunCam for PDH. They have weekly course specials for $9.95 for up to 4 PDH's per course. Michael
  6. I have the 2001 Mechanical Engineering Sample Questions and Solutions. This is the well sought after practice exam that everyone is looking for. Current pricing on Amazon is approx. $105 shipped. I paid $150 back in 2016. I will let it go for $95 shipped. SOLD to Koz332 I also have a 2011 ME: TFS NCEES Practice exam that is practically new. $25 shipped SOLD to TBauer Lindeburg 13th Mechanical Engineering Review Manual for the PE exam. Book has some writing in it (corrections via published errata) and chapters are permanently tabbed but is in very good condition, otherwise. $150 Shipped Lindeburg Practice Problems for the Mechanical Engineering PE Exam, 13th Ed. Excellent Condition. $75 Shipped Lindeburg Engineering Unit Conversions 4th ed. Excellent Condition. $30 Shipped Also have a set of Ashrae Handbooks 2008 (HVAC Systems and Equipment), 2009(Fundamentals), 2010(Refrigeration) and 2011(HVAC Applications). I would like to sell as a set. All books come with CD's $140 shipped. If you buy it all (special bundled price of $350 shipped), I will throw in pre-printed and spiral bound Index and Appendix from the MERM 13th edition for free. (excellent Quality) Michael
  7. I do... Message sent a few days ago.
  8. I have the 2001 Mechanical PE exam book. Are you looking to buy?
  9. Slay, I think 6.4 is a typo. I looked up the Leq for the elbows and was only 4.6 ft each. He is also using "typcial loss coefficients" from table 17.4 in the MERM. I looked at the problem earlier. I had some questions too. Is the Kentrance given as .5? Why could we not use a leq=9.5 ft from A-54 in MERM. It is a square mouth inlet.
  10. I am looking at the external pipe heat transfer. With an 80F external wall pipe temperature in a space that is somewhat colder that -320F. There should be an increased transfer rate above that of the radiant heat transfer: (a) natural convection - Assuming no velocity is induced from the expansion of the Nitrogen (b) quasi forced convection from the expansion of Nitrogen. Hope that makes sense...
  11. I just think problem needs to state, neglect the convective heat transfer...
  12. So we were to ignore the convective heat transfer portion of the problem? The flashing of the Nitrogen should have induced a velocity in the chamber and enhanced the heat transfer. Similar to example 37.1 in MERM... On page 37-4 thru 37-6.
  13. I would like to see the solution for this... I must be making this more difficult than what it is.
