Discussion Overview

The discussion revolves around the feasibility of a thermal process based on Carnot efficiency and work output metrics. Participants explore the relationship between theoretical efficiency and practical outcomes, referencing specific calculations and concepts related to thermal efficiency.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant presents a calculation of efficiency using the formula 1 - Tlow/T high, arriving at an efficiency of 5/6.
  • Another participant questions the significance of Carnot efficiency and whether any process can exceed this theoretical maximum.
  • A participant expresses uncertainty about the importance of Carnot efficiency but agrees that no process can have an efficiency greater than this value.
  • There is a suggestion that the feasibility of the process should be assessed based on both the Carnot efficiency and the calculated efficiency from heat input and work output.
  • A reference to a Wikipedia article is made, indicating that it contains information on the importance of Carnot efficiency.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the importance of Carnot efficiency or the feasibility of the process based on the given metrics. Multiple viewpoints regarding the relationship between theoretical and practical efficiencies remain present.

Contextual Notes

Some assumptions about the definitions of efficiency and the specific conditions of the process are not fully articulated. The discussion includes unresolved mathematical steps and varying interpretations of the significance of Carnot efficiency.

Hi

Can please give me the idea for solving these questions

617360649.jpg
 
Physics news on Phys.org
I have efficiency = 1 - Tlow /T high





so 1 - 200/1200


efficiency = 5/6

Carnot efficiency = w/Qh

20/40 = 0.5

then what the next ?
 
Why is the Carnot efficiency important? Can a given process have a greater efficiency than the Carnot value?
 
hi

I don't no the important but I can not the efficiency greater than the Carnot value
 
So, based on the Carnot efficiency of the process, and the efficiency determined by the heat input and work output, is the process feasible?

BTW, if you read the wiki article, it tells you why the Carnot efficiency is important.
