What is a Carnot Engine and How Does it Work?

Click For Summary
SUMMARY

A Carnot Engine operates between two temperature reservoirs, and its efficiency is determined by the temperatures of these reservoirs. In the given problem, the maximum temperature is 700K, and 450kW of energy enters the engine while 300kW is rejected. To find the sink temperature, one must apply the Carnot efficiency formula, which relates the temperatures and the work done. The sink temperature can be calculated using the formula: T_sink = T_hot * (1 - (Q_cold/Q_hot)), where Q_cold is the rejected power and Q_hot is the input power.

PREREQUISITES
  • Carnot efficiency formula
  • Understanding of thermodynamic principles

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.
