2 - Types of air breathing aircraft engines and their uses
In this video, a general overview of the types of air-breathing aircraft engines is provided and some of their uses are described. First, the principles of flight are briefly described to identify the purpose of air-breathing propulsion engines. A free-body diagram is used to visualize the forces acting on a flying object. Next, 4 types of air breathing engines are identified and described in detail. The components and operation regimes of each engine are briefly outlined. This video is intended to be an introduction to each type of engine. Future videos will describe how these engines work in more detail

How to properly name Matlab Variable | Matlab Tutorial 9
Переглядів 3,5 тис.9 років тому
In this matlab tutorial video, we are going to talk about the proper way to name a variable in matlab. We start by describing several incorrect naming conventions and then explain keywords and their impact on your variable making! Basically, keywords are overlords and you cannot change them. We also talked about how you should avoid variable names that are existing functions. Remember to use ex...

In this matlab tutorial video, we are going to talk about how you can keep a diary of your command window events in Matlab! Sounds kind of lame right? wrong! this is awesome! with this diary, you can record the output of your code as it shows on your command window. You can come back later and see what you did, and even compare results of different diaries if you have some sort of automation pr...

In this matlab tutorial video, we are going to go over how to continue typing a command or line in your script on the next line. Often you don't want to finish your matlab statement, but you are running out of space. By using the matlab ellipsis, you can get around typing one massive line, and continue typing on the next line without running the command. In the tutorial, we go over using the el...
How to call a Matlab Function | Matlab Tutorial 5

    Thanks for the video. One question: So what if the 1atm was not provided by the piston but just simply air? If I look up properties of water under 1atm and say 25c in the diagram I get liquid water only. However, we know that in fact once equilibrium is reached some water will have evaporated so essentially I'll have vapor and liquid. How is this reflected in the phase diagram?

      @@jackparty69 when you deal with dry air, basically it's like assuming that it comes from a hot temp. But, if you want to get it, you then remove the moisture- humidity from it, so it becomes dry air, this one it's helpful for some industrial stuff, but it's pretty complicated, and it should be studied carefully because if you use it for a room and it's not well calculated, it can hurt people badly starting with your skin, and so on. Basically molescules of air are bouncing faster as dry air it's assumed to be at higher temperature than humid air, this matter of energy ends up hurting your skin, and it's hard to breath. Usually in nature, there is not dry air, as it always possess some humidity %

    • @michael279
      @michael279 5 років тому

      it is the time vector that is passed into the function. time(2)-time(1) gives you the time increment per sample and thus you can calculate the sampling frequency fs = 1/Tinc. This doesn't have to be time(2) or time (1), you can also take time(40)-time(39) or in generally time(n+1)-time(n).
