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...

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!!

Thanks Slay! This clears it up. 

Hi MattW, I will certainly do that! If you're considering the Slay the PE Bundle you should check out this contest.  If you send @Slay the P.E. the correct solution he will provide you a link for 50% off.  I will keep you updated.  I am going to finish up the NCEES Practice Exam this weekend...

In this question you need to figure out the enthalpy at one of the states.  The state where I’m having trouble specifies a temperature of 100 degrees F and a pressure of 25 psi.  The solution uses Appendix 23.A in the MERM (Saturated Steam by Temperature) and uses the “Saturated Liquid”...

Wanted to start this post as a sort of study support group for anyone taking the April 2019 TFS Exam.  I did not see one currently started so I apologize in advance if I missed it.   I'll start this thread off with my current study plan: 1) Started right after Christmas by jumping into the...

We use Microstation and do many designs in 3D.

This is how we size transformers.  Assuming a 2-winding transformer, your primary would be: Amps= (MVA*10^6)/((kV*10^6)Sqrt(3)). For a 3 winding transformer, you would need to look at the manufacturers drawing to figure out the MVA on the tertiary then use the same formula.

I think you're correct.  The solution could have been a little simpler by using (PD)/(2T) to obtain 49kPa. 49kPA equals .049 MPa.

My advice is concentrate on Perfecting the NCEES practice exam and nothing else!  The Lindeburg type books are nice but are overkill and destroy your confidence. When I studied for the FE I practiced on a computer with the NCEES Reference Manual on the screen so I could mimic the test format. ...

I am! Message sent.

Wow, Thanks Audi Driver, this really clears things up! In case this link ever goes away, I am summarizing the Ebay link below: Principles and Practice of Engineering Mechanical Engineering Sample Questions (NCEES, 2001) ISBN:1-932613-13-7   NCEES PE Mechanical Engineering Thermal and Fluids...

Can anyone provide a summary of the Mechanical Thermal Fluids NCEES Practice Exams? I currently have the one that was ordered this year which I am guessing is the 2016 exam. What is confusing me is, I want the 2001 practice exam.  I see old posts that show pictures of it which look like...
