JoshTheEngineer | How To: Calculate Wood Density @JoshTheEngineer | Uploaded July 2016 | Updated October 2024, 2 hours ago.
In this video we will calculate the density of a piece of wood that we can use to build the Magic Wine Bottle Holder (see videos below).

Can we approximate the exit Mach number of a rocket nozzle knowing only the area ratio? With a few assumptions, we certainly can! In fact, if we know how the area changes along a nozzle from the throat to the exit, we can calculate how the Mach number varies throughout the entire nozzle.
NOTES
► Ill make sure to never use my orange marker again
► If you download my Method of Characteristics MATLAB code from my GitHub (link below), you can see that the results of both match very closely!
