Intermediate Thermodynamics Questions & Answers  




I guess what you mean is whether the water mixes with the butane. The answer is no, the water remains in the cooling jacket and does not mix with the fuel or the combustion products (the combustion takes place in one duct, while the water flows in another duct surrounding the first one). I already explained this in class... I'll give you 0.5 point bonus boost for this question.




Hm, the question doesn't make sense. Explain better what is the problem — I didn't mention about the volume but the mass flow rates. Also, typeset your mathematics correctly.




I strongly recommend not to use theories that I have not covered in class... All problems in the assignments and exams can be solved using the theory shown in class — do that and you'll score very well on the test! I will not give you a bonus boost for this question because it is out of the scope of this course.




Your question is not so clear, you should give more details. But I think the problem in this case is that you are mixing two strategies together. To find $\overline{v}_2$ and $T_2$ try to use only one strategy: you can use either Van der waals or the generalized compressibility charts, but try to avoid using both on top of each other. The generalized compressibility charts is the strategy that is the most accurate and should be preferred in this case. I'll give you 1 point bonus for this question.
