4F30.96 - Carnot Engine

Code Number:
4F30.96
Demo Title:
Carnot Engine
Condition:
Good
Principle:
Carnot Cycle
Area of Study:
Heat & Fluids
Equipment:
4 Cylinders with Cork Plungers, Colored Blocks (Heat Sinks), and Computer Program - Thermodynamics.
Procedure:

The cylinders with the plungers and heat sinks are used to show the Carnot cycle at different stages.

The computer program 'Thermodynamics' has a good computer animation of a Carnot cycle complete with temperature and pressure curves.
