astronuc, thanks for the help. i found that formula in my book burried in a page of derivations. I'm pretty sure its the right one because my answers were very very close to the ones given. thanks!

Thermodynamics--ideal gas tables problem says: 6.25 employing the ideal gas model, determine the change in specific entropy between the indicated states, in kJ/kg K. Solve 2 ways: use the appropriate ideal gas table, and a constant specific heat from Table A-20. (a) air, p1 = 100 kPa...

thermodynamics--using ideal gas table problem says: 6.25 employing the ideal gas model, determine the change in specific entropy between the indicated states, in kJ/kg K. Solve 2 ways: use the appropriate ideal gas table, and a constant specific heat from Table A-20. (a) air, p1 = 100...

yes that is exactly the kind of info i need! most of the other students in my class have the solutions manual, but i chose to do all my homework myself. i usually look up the final answer in the back of the book before i start each problem. so i know when i have the right answer. i just...

i can do alright on the homework problems because i have a lot of time to think about them. the exams are open book, open notes, but not a whole lot of extra time. i always end up feeling like there is one too many unknowns in the problem. since i have not been able to find a flowchart like i...

I'm taking a 300 level introductory course to thermodynamics (i am a mechanical engineering major). I am having trouble using the tables, such as knowing when to go by pressure and when to go by temp, etc. i know a lot of this just comes with experience. but i was wondering if there was a...
