Question
Consider the T-S diagram of a refrigerator unit. The working flid is R-22. The refrigerator operates between a low pressure of 0.60 bar absolute (measured in the evaporator) and high pressure of 18.0 bar absolute (measured in the condenser). Assume negligible pressure loss in either condenser (path 1 -> 2) or the evaporator (path 3-> 4). A throttle controls the pressure change between states 2 and 3. A perfectly insulated compressor provides the work for the cycle (Path 4->1). The quality of state 2 is 0.00 and the quality of state 4 is 1.00.

1) What is the quality of state 3?
2) While the cycle is internally reversible, is the cycle plus surroundings completely reversible? Briefly explain.
Summary
The question belongs to Chemical Engineering and it is about refrigeration unit. The unit operates at low pressure of 0.60 bar and high pressure of 18 bar. The questions are about the quality of state 3 and whether or not the cycle and its surrounding completely reversible.

I hugely owe to HwA for clearing my concepts as far as accounting entries are concerned. Previously I was not sure in which side of the balance sheet I need to put things like “labour overheadâ€, “capital investmentâ€, etc. But now, thanks to HwA, everything is crystal clear.
I had to submit 7 pages essays due in 2 days. TheReliableTutor.com made it possible without any stress. The assistance was excellent and I really appreciate your hard work. Very much satisfied with the service and I’ll recommend everyone.
Being a student in the Accounting and Management program I desperately needed help with writing my Variance Analysis – Performance Metrics assignment. The online managerial assignment experts at TheReliableTutor are very professional and clear in their communication and greatly helped me in understanding the assignment questions for the variance analysis assignment before starting to write the assignment essay. Their prices are also right for a student like me on a tight budget.
I was a bad place with my electricity assignment and was not sure how to apply the laws to get the numerical assignments done. Then I came in contact of one of my seniors in my college who told me about HwA. The service I got here was awesome and more than giving me a A in my assignment they also treated me with respect and helped me learn a lot.
I was badly stuck with my tax credit assignment solution when I came across HwA. I was happily surprised to see that this website has taxation experts from New Zealand itself and that uplifted my confidence in this. The assignments all got good feedback and now as I am pursuing my PhD also, I seek constant help from them.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
