This being the case, in the 11 weeks left what percentage of my time should be on breadth subjects versus Thermo/Fluids (what I am taking)? Should I try to shoot for 2/3 my time on TF problmes and then the remaining 1/3 on MD and HVAC?
Depends, how comfortable are you with TF stuff versus MD? I really think you're overanalyzing it. The morning session really couldn't be any easier. I posted before that if you use more than 1 equation to solve stuff on the morning session, you're doing something wrong.
If I was taking it again, this is what I'd do:
1. Read the MERM chapters that are applicable. Dont get bogged down on the stuff in the second half of the non depth sections. Read through it and try to understand it all, but if not dont worry about it. You'll figure it out when you do problems.
2. Take the 2001 Exam and all depth modules except HVAC NOW so you know what to expect.
3. Work Problems until you cant anymore with an emphasis on:
A. Morning session - basic HVAC problems (do the 6 min solutions breadth), TF - basic cycles, thermal expansion coefficient, basic heat transfer (conduction, convection, radiation) basic head loss problems, basic pump power problems, basic heat exchangers. Again see the term basic. When I say basic, I mean basic and I can't stress this enough. Just about everything in thermo and heat transfer you can solve using equations that relate Qin = Qout. Know how to convert quickly between cfm and gpm or gph. Know what throttling, adiabatic, compression, expansion, and various other terms mean in terms of what happens to h, s, T, P, and V, not just what the definitions are.
B. Afternoon session - Statics (truss, catenary cables, etc), Dynamics (find coefficient of friction, stopping/skidding distance, angular velocity problems, conservation of momentum, Vibrations (natural frequency, displacement), Solid Mechanics (column buckling, beam bending, moment of I), Materials (stress strain and associated curves, young's modulus and elasticity problems, elongation, material properties), and Machine Design (gears, springs, bearings, fasteners, pressure vessels, and fatigue)
4. Do the 2008 exam and all depth modules except HVAC
5. Spend a day doing engineering econ problems. Do about 10 of them and you'll know how to do figure them out. These are free points.
6. Spend a day reviewing and thinking through basic engineering concepts. Ie. How does moment of inertia change if you double the height of a beam, which beam stretches more given E1 = 2*E2, things like that.
If you know that stuff I put in there cold, you will most likely pass. It sounds like a lot, but it's really not. The NCEES exams are your best friends. The concepts in them will show up over and over, but they'll change the numbers.
