Pearson VUE Professional Test Centers Close in the United States and Canada
Pearson VUE professional test centers in the United States and Canada are now closed and will remain closed until April 16 or...
Page 383 and 385, note 3, Saturation temperature DeltaT for other capacities and equivalent length:
The equation in the NCEES reference manual is DeltaT = Table DeltaT*[(Actual Le/Table Le) * (Actual Capacity/Table Capacity)]^1.8
According to the ASHRAE refrigeration handbook, the equation is...
Yes that makes sense. For some reason I had in my mind that it was a saturated liquid at 281F entering. Thanks! This problem definitely took me longer than 6 minutes, but that ok, it’s a great problem.
For the enthalpy I took hf at 50psia and subtracted the sensible heat from 281 to 70. But...
Here’s what doesn’t make sense to me about this problem (unless I made a mistake somewhere).
Based on the information given, the water vapor in the exhaust gas would condense at 134F. Yet the saturation temperature of the water that is evaporating is 281F. So it’s impossible to get the...
I haven't used any resources from Slay the PE. But if I had it to do over again I would have used Slay the PE for my practice problems. The PPI learning hub problems are filled with errors (at least in the HVAC section). I deal with heat exchangers almost everyday at my job and I'm pretty...
According to the NCEES syllabus, fuels and combustion are fair game on the HVAC exam (see applications/equipment and components/boilers and furnaces/fuel types and combustion). Inorganic chemistry...I'm not studying that, but maybe it is helpful for combustion problems.
I'm taking the HVAC exam...
My best advice is to abandon the English system of units altogether. I almost never use English units at work. I just convert the answer to English at the end. That's the easiest way to stay out of trouble. But that doesn't work too well on the PE exam, especially the HVAC exam.
I agree I think people should take the exam that is closest to their current work or expected work if they are taking the exam prior to experience. It’s just difficult to choose between TFS and HVAC for some people. It was a difficult choice for me.
Can you explain what you mean by studying smarter? Did you just not do enough practice problems the first time? Or did you not focus on the right types of problems?
The answer to your question lies in the diagnostic report that NCEES gave you. What areas were you below average in? What areas were you average or above average in? If you were below average in all of the HVAC stuff but average or above average in all of the overlapping topics (like fluids...
