    PPI Mech Practice Exam 3rd Edition - HVAC+R Problem 50

    Yeah I'm working through these problems right now too. I remember this one, that would be a very leaky crawlspace if that was CFM, not CFH. Let me know when you get to the rankine cycle problem and determining the efficiency. I think its like #61? I don't understand their efficiency equations...

    When to use psychrometric quick equations

    I have gone through the HVAC 6MS three times now and both NCEES 2016 and 2001 practice exams a few times, plus Justin Kauwale's materials. I'm taking the test in Oct. In the NCEES practice tests they mostly use the quick formulas in their solutions. I noticed each practice test had one problem...

    Do these numbers seem right? Heat load calc

    A nightclub is a great example for HVAC engineers just learning load calcs, because it clearly shows how much the people and ventilation drive the cooling load. 290 seems like a believable occupant number for 5000 SF nightclub. 290 people in a nightclub setting are going to be such a high load...

    Is the Machine Design and Materials exam less popular?

If you're doing MDM, chances are you're probably in the manufacturing field, where you don't need a PE license to design tools, processes, parts, etc... for large company (Honda, GE, etc...) Some companies may have it as a requirement for you to climb...

    October 2017 HVAC & Refrigeration

    Another question as I get more into this process: Anyone got a link to a good printable psych chart? I've got a bunch of nice laminated ones here at work, but I'm not sure if they let you bring those since they're not bound? (Ohio test). I'd like to find a nice, readable 8.5x11 one just in case...

    October 2017 HVAC & Refrigeration

    Question for those more familiar with all the different practice exams out there: Is the current NCEES practice exam that you can purchase on the NCEES website what you guys call the "2011 NCEES practice exam" or is it an updated version? If so, is there a place I could find the older 2011 one...
