This is the eighth video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We code the radio button for showing the camber line of the airfoil. We also code the Exit button.

![Explained: Continuity Equation for Axisymmetric Conical Flow [Taylor-Maccoll]](https://i.ytimg.com/vi/f79k_ZWtCdc/mqdefault.jpg "Explained: Continuity Equation for Axisymmetric Conical Flow [Taylor-Maccoll]
The continuity (conservation of mass) equation was derived in a previous video. Since the Taylor-Maccoll problem is formulated in spherical coordinates, the conservation equation needs to be recast in terms of spherical coordinates. A few of the assumptions discussed in the previous assumptions video are used to simplify the equation to a useful form for this problem.
The links to relevant videos can be found here.

The acoustic waves generated from the space shuttle as it lifts off have the potential to damage both the launch structure as well as the shuttle itself. Water is used to absorb some of this energy to ensure a safe launch.
After seeing a different view in a video, it appears that the SSME exhaust hole water nozzles shoot water horizontally across the hole from the sides. The nozzles look like theyre located towards the top of the exhaust hole.
A couple videos that have excellent footage of the structure can be seen below. Note: I would turn down your volume a little before clicking the links because youve probably turned it up to watch my videos.

Croccos equation (under our given assumptions) led to an expression regarding the irrotationality of the flow. That is, the flow is free from rotation. Expanding the expression that the curl of the velocity field is zero, another expression relating the velocities flow can be obtained.")
