I was reviewing example 305.11 of the Goswami Book, and have a question. I understand the problem, other than where it says that Magnesium Bicarbonate requires 0 moles of Na2CO3. reviewing the equations on page 592, it appears that one mole of magnesium bicarbonate is needed for one mole of...

I did OK with chemistry in school, but have revisited it in my studies for the PE and am a little stressed about it. If I am going to "get" anything on the exam, what should I be looking at in my last week?

I am feeling pretty good about the exam right now, but am having trouble with sludge thickening and equalization basins. Could someone please give me a "for dummies" refresher on these topics? I've done lts of digging and am not getting it... Thanks in advance!

The first part of the year, I made myself a study schedule, and outlined what I would do to prepare for the PE exam. I basically gave myself two weeks to do each subject, and left a month at the end pretty “open” for last minute review. I’ve been through the “breadth” section of the 6 minute...

I am seeing on here that there are several definition questions on the afternoon portion of the WR/ENVA exam, and was considering bringing a general science/engineering dictionary with me. I already have the Metcalf & Eddy wastewater book, plus the all-in-one and CERM that I am bringing in...

I’ve talked to several people who have taken the PE exam over the past year, and every one of them tells me that the Sample PE Exam by Lindeburg/PPI is “Way harder than the actual exam”, and that when they took the practice exams towards the end of their studies, they were pretty shocked by the...

I'm working through the NCEES outline and some example problems (using Goswami and CERM) for the structural section, and am having trouble finding what I need to focus on. I find the NCEES outline to be a little vague (admittedly it may be due to my lack of experience on this subject...) I...

I got a set of problems from a co-worker for the construction section of the PE exam, and have a couple of questions. 1. when solving concrete mix problems, once you've gone through all of the steps listed in the CERM and determine the volume of your batch, you can go in and determine the...

I am taking the PE exam in April (Enviro/Water Resources), and am gathering materials together. A co-worker lent me his Civil Engineering Reference Manual, dated 2002 (8th edition I believe). Does it really matter if I use this one versus paying for a new or slightly used one that is more...
