Only studied the parts that were covered by practice exam/practice problems using the MERM. I think if you know how to do a free body diagram and understand basic loading, it will get you far. Remember to know where to get information during the exam if something does show up. 

I passed the exam (October 2018) and I want to thank everyone who helped me (Thank you!!) in this blog and also add in my two cents. I took the TFS module based on my background even though my current job is nothing related to TFS. Started studying mid July, serious studying in August giving me...

Congratulations! & how did you know the "88 percentile"?

Thank you! and yes I did notice in the NCEES practice problem we are given all K or equivalent length values

yes 6.4 was my typo, it should have been 4.6 but I am still not getting the solution values.  I opted to use k values, so I have: 5-long radius 90 elbows: 5x0.9 = 3, 1 gate valve - 0.19, 1 sharp edge  - 0.5 Total k = 3.69 Total loss = kv2/2g = 14.68 The the 40ft length loss comes to: 9ft so...

Hello, this is the...

Condensed Problem statement: 40ft of 4in sch. 40 steel pipe containing five long radius 90deg. elbows + one gate valve + one sharp edge. V=16ft/s, f=0.019 Book Solution: K_entrance = 0.5 and all others included in the equivalent length as 40ft + 5(6.4ft) + 2.5ft = 65.5 and total head loss...

Thank you!  I did do those exact steps, went to the compressed tables and couldn't find the answer since it was too low. Appreciate the help from both, will keep this in my notes

Yes, but at 40C, 1MPa>P_sat so wouldn't it still fall under compressed liquid? Hence my confusion.. Thank you!

How do you know whether to read h_f at 1MPa vs. h_f at 40C? Thank you

Thank you! I think I was staring at it for too long, now that I look at the problem again, I see how simple it is. I read it wrong, so grateful for everyone's responses and I hope to return the favor! And thank you for the links, will download the charts :)

Hi, I tried google and all my references but I don't understand this: on the 13th edition of MERM, example 38.4 has: .....40F (A)dry bulb and 35F (B) wet bulb are mixed ........etc The solution has a specific volume of A as 12.65 ft3/lbm which makes sense. Then it has specific volume of B as...

Thank you both!

For those that took the Thermal Fluids Exam in the new format, how much of HVAC topics do you need to know? According to the PPI study guide, it looks like all of MERM's HVAC section is fair play, is this accurate? Thanks in advance

The Thermal study guide listed in the PPI study schedule lists the topics of MERM chapters 40-44 that are labelled under HVAC. Are HVAC topics fair play for the thermal test?
