Homework Help Overview

The discussion revolves around understanding the concept of a Carnot engine, specifically in the context of a problem involving temperatures and power inputs and outputs. The original poster presents a scenario with specific values for maximum temperature and power rejected, seeking to determine the sink temperature.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the original poster's understanding of the Carnot engine and question the relevance of formulas found. There is an emphasis on the need to grasp the underlying principles before attempting to solve the problem.

Discussion Status

The discussion is ongoing, with some participants emphasizing the importance of understanding the Carnot engine conceptually before proceeding with calculations. Guidance has been offered regarding the need for foundational knowledge, and a reference to a textbook has been provided.

Contextual Notes

There is an indication that the original poster may lack familiarity with the Carnot engine, which could affect their ability to engage with the problem effectively. The mention of a textbook suggests a resource constraint in understanding the topic.

i have this example problem...and i want to know how to answer this problem :confused:

a carnot engine is operated with its maximum temperature equal to 700K and 300kW were rejected. what is the sink temperature, if 450kW enters at the upper temperature.

tanx for your help..

actually i have no idea what carnot engine is all about...i look for some formula but its not related with the problem...:frown:
 
You can not go about learning science by plugging numbers into formulae without understanding the principle involved. You must first understand what a Carnot Engine is before you can attempt to answer this question.

I'm sure the recommended textbook for your course will cover this.
