Heat Transfer and Fluid Flow

heat transfer theory in education


One of the favorite classes I took in school was called Heat Transfer and Fluid Flow. Sounds boring, I know but it really helps to explain the world around us when we understand things like "why is the suns rays hot?" "how do ceiling fans help me feel cooler and lower my electric bill?"

It really comes down to understanding the first law of thermodynamics in that energy cannot be created nor destroyed but only transformed from one form to another.

Also, understanding that heat is always moving to a colder area, and at different rates. For example, heat will transfer into your house faster if the walls are metal than if they are wood. It also depends on the thickness of the walls. Here is a great video showing how what we perceive in regards to how hot something feels is often not reality.
