Walkthrough for Bellingcat's 'Shattered Glass' challenge

Hi, welcome to this write-up for the Shattered Glass challenge from Bellingcat. Here you can see my thought processes and what steps I took to get to the answer, but of course there are many different ways of reaching the same results. The challengeWe've been asked to give the minimum peak overpressure required to shatter glass (in kPa). All of these terms were new to me, so I decided to first learn a little about what we were dealing with. I googled for: minimum peak overpressure kpa This led me to this link from a blasting mats manufacturer that explains a lot of the terminology. I saved some relevant parts into my notes: “Blast pressure is the instantaneous rise in air pressure above the normal atmospheric pressure caused by the rapid expansion of gases from an explosion. […] Typical atmospheric pressure is around 14.7 pounds per square inch (psi) at sea level, so any pressure created by an explosion above that baseline is classified as overpressure.” “The peak overpressure of a…
