I can attest to this!

Getting into the Fluids portion of the Slay The PE test prep and so far so good. It starts out basic but I am finding that this helps me make sure I have the concepts right before getting into the more difficult problems.

This is correct from what i've seen too. Generally, the rule of thumb is to aim for 70% (56/80).

Welcome!The only thing I would reccomend for the mechanical FE exam is the NCEES practice exam and the NCEES provided reference manual.

It sure is, although most of them are Civil engineers who use their degree daily. I work in Electrical and am taking the Mechanical exam so naturally have to study harder.

Interesting! Someone posted that recently but I missed the top part!

Its not planned anymore, NCEES has announced that the exam will be computer based in 2020. I'm signed up to take the Mechanical TFS exam in April. You should be fine. Just study as if you're only taking the exam once. That's what I am doing. I've had colleagues who have passed the exam tell me I'm studying too much but I'd rather do that then take the exam more than once. Good luck in your studies!

Oh man, more incentive for me to pass the April Exam.

Ok, I figured it out. If you use the the U.S. Customary version of the Bernoulli equation as shown in the MERM, it simplifies to P1=p1h1 + (p2v2^2/2g) where P=pressure and p=density. 1) Density = 62.4 * 1.03= 64.3 lb/ft^3 2) Convert knots to ft/sec to obtain 50.634 ft/sec 3) Convert 14.7 psi to psf by multiplying by 144 to obtain 2116.8 psf. 4) Plug and Chug

Please forgive my ignorance, but I thought g/gc was equal to 1? That's the way I've been studying the NCEES 2016 Practice Exam and this is the only problem I cannot get to workout.

Some sort of conversion is necessary. If you just used units of gravity and density, you would end up with an answer of Lb/ft-Sec^2.

I'm a little lost as to why gravity must be converted to slugs/ft^3. It seems that you do not have to mess with this with all the other formulas in the MERM. Where does the formula for this show up in the MERM?

This solution is way easier to understand than the NCEES solution. Thanks @justin-hawaii!

I’ve “mastered” the 2016 TFS NCEES practice exam. Now I’m going to move into the @Slay the P.E. TFS bundle. While im studying I’m going through and building my notes for the exam and highlighting key equations in the MERM.

Thanks Slay!!
