No. They just said I could not take the exam unless I took the missing college-level classes. I think after taking the classes, I still had to show experience time, but I don't remember that well. This was over 10 years ago.

Hi all, In case you didn't know, every once in a while, NCEES updates the errata sheet for their practice exams, but makes no "official" announcement (that we know of). Check your discipline exam errata in their website

Hi all, In case you didn't know, every once in a while, NCEES updates the errata sheet for their practice exams, but makes no "official" announcement (that we know of). Check your discipline exam errata in their website The Mechanical TFS and MDM were updated November 22nd, and 23rd...

The “fluid power” (also known as "theoretical power" or "water horsepower" if the working fluid is water) is the power the pump provides to the fluid. The "shaft" or "brake" horsepower is the power the motor provides to the pump. The shaft power will be slightly larger than the fluid power...

The pressure rating of the piping system will have to be greater than the highest pressure in the system. The greatest pressure in this system is at the pump discharge. The pressure at the pump discharge is 20psi + Δp_pump, where Δp_pump is the pressure rise across the pump. With the given...

Because in an impulse turbine the power is maximized when v=(1/2)v1

I don’t think that information is there. Also, you should be using version 1.6

Your assessment is correct. The equation in the NCEES solution is wrong. OA load is calculated with the enthalpy difference between outside and return air.

500 bar does seem excessively high.

Agreed. That made looking at the steam tables terribly inconvenient.

Following up on this, Section 4.5.2.1 Internal Combustion Engines has been cleaned up a little and now they provide a helpful definition for the parameter "n".

Here's a preliminary list of things I noticed. Other things might come up upon further review. I was focusing only on Thermal-Fluid Systems: Section 2.15.6 Vibration Isolation—Fixed Base is completely new (this is 100% irrelevant to TFS) Section 10.5.2 Incomplete Combustion has been deleted...

You should get it if your exam date is after April 1, 2022.

Ok, I see now. As you have also noted, the table you linked uses the Darcy-Weisbach equation and the table in the reference handbook uses Hazen-Williams. One can find references recommending C=150 for Hazen-Williams in new steel pipe. Using C=150 brings the results a lot closer. It is worth...

@ZDG For 8-inch pipe, (ID=7.981”) with Q=1000 gpm, the Hazen Williams equation with C=100 yields 3 ft head loss for a length of 100 ft, matching the value in the table. From 3.4.2.3, Hazen-Williams for 1 foot length is: h = 10.44 (Q^1.85)/(C^1.85*D^4.87) If you plug in the numbers you’ll see...

What error do you see in this table?
