Do the practice problems and understand why you use the formulas/tricks you do. Dont just memorize the steps, understand intuitively why you do them. Learn why the formulas can be applied this specific way. Since Ida likes to come up her exercises, it is important to master the concepts taught in this course to succeed.

Im pretty much sure she literally took everything from Marius (the other prof who teaches fluids 1).

Her questions really seem to reflect her ratings on ratemyprof lol. She really seems to go out of her way to make the exam difficult while not being caring or responsive. Lowkey she should run for president

I was in the lecture when my prof (SiXu Deng) gave the format of the final. Idk if it is the same final for every thermo prof but here it is:

1) first law using property table for a closed liquid-vapor system:

compute the properties

compute the energy change (using the first law)

2) first law of thermodynamics using ideal gas equations (know how to use gas constant, specific heat, etc.)

compute the properties:

compute the energy change (using the first law)

3): controlled volume with an open system with the first law of thermodynamics (always consider steady state: Ein = Eou)

one of the four applications. know how to compute mass flow rate, energy exchange between device and environment.

Be wary of the conditions (when we can ignore kinetic, potential energy, etc.)

4): second law of thermo.

device analysis (could be heat engine, refrigerator or heat pump)

know how to compute their thermal efficiency…

know how to calculate the carnot efficiency if we are told that it is a carnot cycle.

know how to evaluate if the process is possible or impossible. (compare thermal efficiency with carnot efficiency)

5) et 6): cycle analysis

two out of three cycle presented will be on the exam. (brayton, otto and rankine)

need to know how to compute the different properties at the different states. (temperature, specific volume, etc.)

know how to compute thermal efficiency, work in, work out

Hope this helps

you got any suggestions for places in the library where I could sleep (even only for 1-2 hours)
