we aren't allowed to discuss specific questions. I'd rather just wait and find out my results than risk letting NCEES somehow invalidate my scores! Not worth it!

I think I nailed both sections too! However I studied my tail off for many months!

Amen Brother! (Or sister, whatever you are!)

During my preparation for the PE exam (which I am taking in NYC tomorrow by the way), I found myself stressing a lot about not being able to solve questions in the 6 minute timeframe. The first time I did the Lindeburg HVAC practice exam, it took me an average of 20 minutes per question, and 2...

Thanks so much for your help. Not just on this question but on the others too!

MikeGlass1969...Using 1.08 you need to understand the underlying assumptions. You can't always use it. Habib...I guess I just assumed that it would be more accurate to use an average density over the two temperatures, but apparently not!

Yes I've worked hundreds of problems as this point, mainly the MERM Practice Problems, the SMS, and NCEES Practice Exam. However I hear lots of people talking about bringing pre-worked-out problems with them to the test. I thought this was a good idea but am just hoping to get an idea of what...

I was hoping I might get some input on specific problems that people have worked out that they will be bringing to the PE HVAC exam. I've been studying diligently for a few months but just cannot decide on what problems are good representations of the exam problems.

Habib, could you expand on your answer? That didn't do much for me.

I'm sorry, but what do you mean by "adjust air flow with outdoor conditions..."? Thank you for responding.

Can someone please help me out here as I feel like I see contradicting answers. Let's say you have to heat 21,000 CFM from 0F to 50F. When using qdot = vdot*rho*cp*deltaT, do I use the density of 0F air (.086 lbm/ft^3) or 50F air (.077 lbm/ft^3)? The difference is substantial. Thank you for...

Got it!

My original post should read (T_outdoor - T_indoor), as this gives the positive result.

I am hoping you guys can help me. Question 509 on the 2011 NCEES Practice HVAC & Refrigeration Exam seems simple, but I can't quite figure it out. Basically you have a window facing north, east and west, with Cooling Load Temperature Difference (CLTD) at 26, 55 & 72 respectively, and...
