Textbook Problem

A heat engine operates between a reservoir at 25°C and one at 375°C. What is the maximum efficiency possible for this engine?

To determine
The maximum efficiency possible for the engine.

Explanation

Given Info:

Temperature of the low temperature reservoir is 25°C .

Temperature of the high temperature reservoir is 375°C .

The maximum possible efficiency of an engine is the Carnot efficiency.

Formula to calculate the Carnot efficiency is,

ec=1TcTh

  • Tc is the temperature of the low temperature reservoir
  • Th is the temperature of the high temperature reservoir

Substitute 25°C for T
