    Energy/Mass Balances HVAC EXAM

    "I ain't dead yet, Slay"!!!!  Slay speaks truth,  combustion problems had a significant presence on my exam.    I would study these hard. For example be able to calculate the partial pressure of water in the flue gas.   or something along those lines

    Time to fully discharge a Chiller due to leak

    We have to calculate the losses from leaks in refrigeration.  Most engineers figure this in air then convert to Freon.  Use the air tables in the MERM.  The velocity of the Freon through the pinhole with be Sonic velocity up to a ratio of the absolute pressures is .5?    I mean the Mach Tables...

    Practice Problems for Mechanical PE Exam, 13th Ed - PDF format??

    The PDF format of the MERM is only good for 3 years and then expires.  I assume, if there is a pdf form of the practice problems book, it would expire in 3 years also.

    ASHRAE Book Purchase

    It doesnt have to be those years.  Can be any string of 4 years in a row.  A 2011 index will reference itself and the 2010, 2009 and 2008. A 2008 index will reference itself and the 2007, 2006 and 2005 books.  Its always itself and the 3 previous years books.. The index is a combined index...

    ASHRAE Book Purchase

    For instance.  If you bought the 2011, 2010, 2009 and 2008 books.  That would be a sequence of 4 books.  The index in the 2011 book would refer to the pages and sections in the 2010, 2009 and 2008, as well as its own year.    If you bought non-sequential years,  the idex will not refer to the...

    ASHRAE Book Purchase

    I took older books in the 2016 exam and was fine.  Not a whole lot changes in the books.  Just make sure you get a string of them, all 4 years in a row, so the newest book would have a proper index that refers to the previous years.

    Best Software for HVAC System Design?

    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.

    TFS Lindeburg #33

    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...
