Here is an example of how to solve a first order ordinary differential equation using Matlab. The function in this case is that dy/dx = – 3 y with the boundary condition that when x = 0 then y(0) = 4. This solution is applicable to solving problem 4.7 in HW8, where in this case, think of the ODE as dZ/dt = – A V[Z(t)] and the initial condition is that when t = 0 then Z(0) = 1.3 m. The term A is just a constant that includes all the other variables, make sure your units are all compatible. You would solve this over the time interval from 0 (tstart = 0) to say 100 minutes (tend = 100) and note when Z = 1m which means the bag is empty. Here is the program ODE

At left are some photos of pitot tubes on the side of a 747 parked at Detroit Metro and one that a student’s friend, an aircraft mechanic, provided. Here’s a news story from ABC about the crash with some animation http://abcnews.go.com/Blotter/air-france-flight-447-crash-didnt-happen-expert/story?id=16717404 and an article from Scientific American http://www.scientificamerican.com/article.cfm?id=what-is-a-pitot-tube .

I messed up my viscosity in my calculation so the correct answer should be 2H = 0.041 microns. Several of you got this answer and if I knocked off a point let me know and I will correct your grade.
