Does anyone have any insight to Boles Thermo II final exam? There is a lot of info its going to cover.

it's just like your tests you take during the semester and you have more time to do it

easy stuff. don't let him intimidate you.

Does He like to combined topics into a single problem. Because there are about 7 topics but the test is only 4 questions.

not really. he'll pretty much just pick 3 topics.

i mean, the whole class is just writing energy balances and solving. you don't even have to be able to read the steam tables for his tests. the only thing that could be a little tricky for an ME is the combustion stuff.

but just as sure as i say this, he'll give you like a combined cycle problem where you use the hot exhaust of a Brayton cycle to make some steam or something. or he could do like a brayton cycle where you have to do the combustion calculations. it's still easy, though. just break the problem into the two problems you've seen before. take the result of the first problem and use it to solve the second problem. i highly doubt that you will see such a problem on his exam, but he likes to throw what he considers to be curveballs at you. students get confused by these problems because they require you to think and not just regurgitate what you did on the HW. usually all he does is pick a weird parameter for you to solve for or swap the info given and the info asked for a problem that's exactly like one you did on the HW.

i would suggest knowing closed system cycle stuff. and i don't mean just memorize diesel and otto. you need to know how to sketch T-v, T-s, etc. for a cycle that he just makes up. he'll tell you what's constant or polytropic or isentropic or whatever and you will need to sketch it, figure out where work goes in and out, where heat goes in and out, and then solve for whatever he asks. it's pretty easy stuff if you don't freak out when you see something you've never seen before.

I took it fall 09.. 4 question final.
1) one of his made-up combustion cycles.. only had 3 processes
2) was a brayton cycle with closed and open FWH
3) was a combustion problem, balancing equations, HHV/LHV, adiabatic flame temp, dewpoint of exhaust, etc
4) was a air cond/refrigeration cycle with external cooling water. he gave us a maximum temp change for the cooling water and we had to find condensation rate and a few other things

it wont be too hard

i think you meant rankine cycle

and apparently i had that class with you. i didn't remember the details of the final like you did, though.

lol i did mean rankine... for doing so poorly in the class i remember an awful lot

when did/will you graduate? I've got a summer classes, and 416 and a few electives this fall and I'm done
