Which refrigeration cycle has a higher efficiency?

AI Thread Summary
The discussion revolves around comparing the efficiency of two refrigeration cycles depicted in a T-s diagram. The first cycle operates at a lower temperature range, while the second operates at a higher temperature range. Participants are asked to provide insights on which cycle has a greater coefficient of performance (C.O.P) or efficiency. The confusion stems from understanding how temperature ranges affect the efficiency of refrigeration cycles. Clarification on the thermodynamic principles governing these cycles is sought to resolve the uncertainty.

The attached file shows a T-s diagram of a refrigeration cycle . Now let us consider 2 refrigeration cycles as shown in the diagram 1-2-3-4 and 1'-2'-3'-4'. Which one will have a greater C.O.P or greater efficiency ?

The first one (1-2-3-4) acts in a lower temperature range , whereas the 2nd one (1'-2'-3'-4') acts in a higher temperature range. Can someone provide me some hint or thought process . Is confused. Someone show me a way . Thanks in advance .

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
