Have you ever wondered what the hot air coming from your computer's fan looked like? This short video shows you what it looks like coming out of the side of my computer after I just turned it on.
You can see the result of some of the heat exchanger fins, which makes the flow look comb-like at the edge of the computer.

![Explained: TdS Equation [Taylor-Maccoll]
The TdS equation is a combined statement of the first and second law of thermodynamics. It relates the entropy, enthalpy, and pressure changes in a system (for the form that we need for Croccos theorem). To keep the big picture in mind, recall that I mentioned that Croccos theorem is a combination of the thermodynamics and kinematics of a flow. This equation gives us the thermodynamics part.

![Calculating Stoichiometric Fuel-to-Air Ratio
How do you calculate the stoichiometric fuel-to-air ratio for a given fuel? In this video, Ill walk through how to balance the stoichiometric global reaction, and then go through an example for n-decane (C10H22), finally solving for the stoichiometric fuel-to-air ratio.
This fuel-to-air ratio will be important for my future videos on jet engine analysis.
