Since I had to pass the ethics take home exam as part of the California application, I can say that the PE Act Chapter 7, Article 1 section 6704 seems pretty self-explanatory, Or section 3732, And finally section 6787, As this issue was described by me, until you hold a license you can't use...

I never heard stuff like that for scores, but I do feel for female engineers. There are a lot of people who feel that female engineers get interviews/jobs because they are such a minority and many question whether a female earned the position or was awarded it. It's an awful mindset and I'm glad...

TFS April 2017, passed (first time taker). IMO you still need to review the basic engineering principles, if you have time. If you are strapped for time you can still skip them, but I would recommend reviewing free body diagrams and statics for sure. Run through as many problems as you...

Mechanical, so I just needed the one :)  

I received an email from the Board on April 7th that stated I was approved. If I had already passed the exam then I will receive my license in 2-4 weeks, if I have not yet passed then I need to inform them when I do. Guess they already have a canned letter for the decoupling. I'm hoping that it...

@Diego26 This is the first test to be decoupled so I doubt anyone has that information, but in the email they said if you already passed it'll be 2-4 weeks. I'm guessing with the holiday it'll be 2-4 weeks after Tuesday or Wednesday of next week, but who knows! Congrats! The feeling of relief...

Glad to know others felt exactly as I did! Ya, I guess it's harsh to say that the material didn't match the stated breadth, but a few questions felt like they were coming out of left field. I definitely made guesses/educated guesses on more problems than I expected to. Good luck everyone.

Anyone take the TFS? I felt that the problems that were really emphasized in the practice exam weren't all that tested in the real exam which was a huge bummer. Definitely felt that the new breadth is deceptive as they threw in a number of other disciplines than pure TFS. Overall, not that...

Thanks, P-E. That's exactly what I did but I did notice I was being dumb and using closed system equations and not open system isentropic, the formula is right there in the MERM.. Regarding 6MS you're right. I started losing confidence which isn't good at this point. Just reviewed some more...

Massive brain fart! Power = Wdot = mdot(h2-h1) I see how they derived the equation with k on numerator.

Interesting, the wikipedia article says that power is related by the cube but then shows the fifth power. I suppose it's a typo, but I'm surprised that it has survived on wikipedia.

MERM 18.45-18.47

Thanks for posting the index, but a huge suggestion would be to allow a PDF print of the appendix for verified purchases! My scanned version looks pretty bad and I wouldn't use it for any of the graphical resources.

Thanks y'all for the detailed responses. I definitely think it's worth bringing this up to NCEES. Like I said, if it wasn't for this thread I wouldn't have questioned my very wrong methodology. Well done!

I am working the 6 minute solutions problem 67 and I was wondering how they derived the equation for power. I knew to use the isentropic equation with P=mdot*work. I canceled out the densities and almost ended up with their equation. Pth = (k/k-1)*Q1*p1*[(p2/p1)^k-1/k - 1] I don't really need...

No, I definitely agree. I don't work with pump sizing so I just had it in my head that parallel means 3xQ and sped through it. Seeing the "correct" answer when going over the solutions cemented that false method in my head and I was happy (didn't think I needed to look back over curve material)...

I see what you're saying now. Hammering through questions I didn't question it and just took 3x the flow rate and moved on. I didn't look too closely at what a properly plotted 3xQ would look like. I'm afraid I'm not any help, then. Perhaps you can report it to NCEES and hope to save future...

From engineering toolbox: Pumps in Parallel - Flow Rate Added When two or more pumps are arranged in parallel their resulting performance curve is obtained by adding the pumps flowrates at the same head as indicated in the figure below. Centrifugal pumps in parallel are used to overcome...

Excuse the crude adobe job, but this was my method. There is no way that I can see that the head won't increase.

This was excellently answered by Audi on this other post, but I wanted to add here in case someone only clicks on this thread. The solution appears to me to be correct. I get 65-70 ft estimating off of the diagram with a ruler (3xdistance measured to the intersection). I'm also not sure how you...
