My plan is: -Complete some MERM problems on: Compressible Flow, Heat Exchangers, Engineering Econ, Psychrometrics -Re-work the depth SMS for T&F -Re-work the NCEES sample exam (for a confidence boost as I made stupid mistakes while earning a low score). 200 hours of studying should be...

This should be an easy question, but I'm having a mental block. Can someone explain the solution for calculating the ash disposal costs for the Pellets? I don't understand why they took the ratio of coal/pellets. Is there another way to solve this? Thanks in advance.

Help! OK, on this problem you're given steam properties at 600deg F and 1atm and water at 60degF and 1atm. YOu're trying to find what the quality of the mix would be using equal parts of steam and water. Finding the enthalpy of the steam is easy b/c we know its super heated. However, the...

In order to help those of us taking the exam with a month to go, please respond to what you plan on (or did) taking as your depth module. (this is helpful when searching archived posts to understand one's perspective on a certain resource) I'll be taking: Thermal Fluids Systems

I love using the Cameron Hydraulic Data book as it saves me a lot of time from calculating the Reynolds Number, Roughness, etc in order to find the pressure drop (in ft.). However, I need some help with using this resource for fluids other than water. 1)When Given a Specific Gravity (other...

Without plotting the design region, can you determine the failure mode? I did the principal stress equation, and was able to determine that the minimum principal stress has a Safety Factor <2. How am I supposed to know that it fails in Shear and Not Principal stress? Problem: a cube with...

I just finished the CODE questions in the T&F Six Min Solutions, and have no clue how to tackle those on a test. I don't have access to these codes. Based on y'alls testing experience, Is this something I should buy? Even if I buy it, I won't have time to read it all!

Where is the equation located in MERM to solve T&F 6min sols #27? mdot=A*alpha*((rho0-rhoL)/L) As I'm doing these problems I'm tabbing the crap out of them, and Reviewing the surrounding areas, but I cannot for the life of me find this equation. Any help would be appreciated.

I calculated this problem using Cameron Hydraulic data. I found the Hydraulic Diameter (Table 16.1 in MERM) for a 2"x2"square cross section to be equal to L. So, Hydraulic Diameter=2". I calculated the flow to be 22.44 GPM. Looking in Cameron for water at 2" SCH 40 Steel (I know its asphalt...

What calculator did you use/prefer for the exam?

In working problems in Chap 29 of the MERM 12th, I found that some ways of doing the problem depend on if you assume isentropic or constant spec heat. In solutions to problem 7 they say to assume isentropic but problem 8 which is an additional portion of problem 7...you are to assume constant...

Long time lurker, first time poster.... Hey y'all! What is your take on the "max time limit: one hour" problems in the practice book? Do you go over those at all? How do the problems in the book compare to the test? Thanks!
