Well, you've already justified using a book that is four editions and maybe 20 years out of date, and I know my comment isn't very useful, but using the 10th edition is probably the worst strategy for being ready for 'anything' on the exam I've heard. Sorry, just my opinion.

Okay, so let me repeat what I think I heard. You're working in Chap. 14, which has a section on (absolute/dynamic) viscosity (section 9), and on p. 14.7, it says, "...the absolute viscosity of gases and liquids is usually considered to be essentially independent of pressure." And, a section on...

I checked the PPI Errata website - Six-Minute Solutions for Mechanical PE Exam Mechanical Systems and Materials Problems is in its 2nd edition, 5th printing. While there are 2-4 errors listed for each printing of the 1st edition, the 4th and 5th printings of the 2nd edition have no errors...

Do you mean the fluid impedance and other odd fluids questions in Ch. 19? MERM12 doesn't have anything on the subject, but MERM13 does explain it in an improved chapter that also now covers the subject of pneumatic systems. In the 13th edition practice problems book, there are 22 chapter 19...

The answers from the two methods can differ significantly, particularly at higher temperatures. If they are close, then it's just a lucky break. The equations can (should) be used if air is considered to be an ideal gas. This implies the specific heats are constant, enthalpy change is a...

My curiosity is piqued, because now, (according to PsychoNumber1), CERM is "... a waste of time ... there is a lot of erroneous information...". Erroneous information? Erroneous means "wrong". I wouldn't want to use that kind of book, either, but where is the erroneous information? Did he/she...

I don't think I've read a recommendation on this board where CERM was described in conjunction with the words "insane", "ridiculous", and "crappy". Could you please explain what you mean with "...grabbing equations on the fly ... that i hadn't really used before ... due to the way they list and...

From the PPI website about CERM: "The 12th edition includes expanded topic coverage, reformulated example problems, and hundreds of new index entries. In total, 84 of the 89 chapters have been revised and updated, making this industry-leading book even more complete and easier to use." And...

PPI's Civil Engineering Passing Zone ends a week after the exam so that participants can say, "Goodbye" to their fellow studymates and "Thanks" to the PZ instructors, as well as ask the inevitable questions: "How do you think YOU did?" and "What color was your pencil?"

You're right. some of the chapters are light on problems, when mastery is the intended result. Lindeburg's Environmental Engineering Reference Manual and its accompanying Practice Problems Manual were "designed" to accomplish several simultaneous goals, including (1) providing a thorough review...
