Making a pulsejet that runs on any aerosol

Image
Firstly, I used an open tin can for the combustion chamber. The tin can was cleaned thoroughly before use, and allowed to dry. Then two metal tubes were used as an exhaust and inlet. The larger tube, with an approximate diameter of 3.7cm, will act as the exhaust pipe. The smaller tube, with a diameter of 1.9cm will act as an inlet.  Next a fuel system must be made. Below is the plan I used to convert 1/4' flexible tubing to 8mm copper pipe. My only supplier of plumbing parts is Screwfix and I could not find a straight adaptor, so multiple adaptors were used to convert the tubing to 8mm, and to accommodate a ball valve. Below is the plan in real life, made with the parts listed above. Next, it is important to crimp the end of the 8mm pipe. This allows for a faster velocity of the fuel entering the combustion chamber. Faster gases have lower pressure, so the Bernoulli effect is amplified. The faster gas effectively sucks in more air, allowing the pulsejet to run more efficiently.  Fo

Making an oil siphoned rocket-based burner

Image
This essay explores the concept of using siphoning as a fuel pump system, examining its efficiency, practicality, and potential benefits. Below is the initial sketch for the burner. Fuel, in this case vegetable oil, is stored in a reservoir. It is then siphoned down a tube into an atomiser, which is then held in front of a stream of low speed, high pressure air. This mixes thoroughly with he oxygen and makes a mixture suitable for combustion. This is then lit by hot gases expelled from the mouth of the rocket, and then exits, creating thrust and massive amounts of heat. The Siphoning Principle Siphoning is a natural phenomenon that occurs when a liquid flows between two containers at different elevations due to the force of gravity. It involves a tube through which the liquid moves, creating a vacuum that draws the liquid upward and overcomes the force of gravity. In the context of fuel burners, this principle can be harnessed to transport fuel from a storage tank to the burner unit wi

Superheated Steam

Image
Introduction: The interaction between superheated steam and a match may seem counterintuitive at first glance, as steam is commonly associated with extinguishing flames rather than igniting them. However, under specific conditions, superheated steam can indeed light a match, revealing a fascinating aspect of thermodynamics and combustion. This essay explores the science behind this phenomenon, examining the critical factors that contribute to the ignition of a match by superheated steam. The Role of Temperature: The key factor in understanding how superheated steam can light a match lies in its elevated temperature. When steam is superheated to sufficiently high temperatures, it becomes an effective heat transfer medium. The intense heat carried by the superheated steam can lead to a rapid increase in the temperature of nearby objects, including combustible materials like a matchstick. Thermal Conductivity and Heat Transfer: Superheated steam has a higher thermal conductivity than air,

My very first web app - an extension for Google Chrome

Image
I have recently made a Chrome Browser Extension and submitted it to Google. To my delight, it was approved by Google and published in the Chrome Web Store within 24 hours since submission. The submission took place on 16 November, 2023. Approval and publishing by Google The app in question lets both students and teachers practise transformation of graphs interactively. All you need to do is adding it to the browser as an extension. Here is the link: 👉 Transformation of Graphs This is how it appears in the Chrome Web Store. Just click the button to add it to your browser: Transformation of Graphs on Chrome Web Store This application visually shows how graphs change while applying certain transformations to them, with the app itself being high customizable. The User Interface of the App The App at work Transformation of Graphs The inspiration behind the app stemmed from the realization that visualizing and understanding graph transformations could be a daunting task for many.

Transformation of Graphs - for GCSE, IB and A Level

Image
 Transformation of Graphs - GCSE, IGCSE, GCE-OL, GCE-AL, A Level & IB Functions - f(x) f(x) = 2x - 3 is called a function of x. Whatever you put inside the parentheses on the left, must replace the variable, x in this case, on the right. E.g. f(2) = 2(2) - 3 = 1 f(0) = 2(0) - 3 = -3 f(-2) = 2(-2) - 3 = -7 f(x+1) = 2(x+1) - 3 = 2x - 1 f(x²) = 2(x²) - 3 = 2x² - 3 f(x/2) = 2(x/2) - 3 = x - 3 f(-x) = 2(-x) - 3 = -2x - 3 -f(x) = -(2x - 3) = -2x + 3 Transformation of Graphs  There are three transformations. They are: Translation Reflection Stretching With this Chrome browser extension, you can transform the following graphs: Linear graphs - e.g. f(x) = 2x - 3 Quadratic graphs - e.g. f(x) = x² - 2x Cubic graphs - e.g. f(x) = x^3 Reciprocal graphs - e.g. f(x) = 1/x Exponential graphs - e.g. f(x) = 2^x Trigonometric graphs - e.g. f(x) = sin(x) Translation Translation in the x-axis: f(x) → f(x ± a) Translation in the x-axis Translation in the y-axis: f(x) → f(x) ± a Translation in the y-axis

Merge Sort

  First things first, Merge Sort follows a divide-and-conquer strategy. It splits the problem into smaller subproblems, conquers them, and then combines the results. This algorithm takes an array of elements and repeatedly divides it into halves until we end up with single elements. It then merges these elements back together, sorting them along the way. It's like a sorting ninja, meticulously breaking down and reassembling the array. Imagine you have an array of numbers, and you want to sort them using Merge Sort. Here's how it works: Divide and conquer: The array is repeatedly divided into halves until we have individual elements. It's like taking a massive pizza and slicing it into smaller and smaller slices until you have bite-sized pieces. Sorting the pieces: Once we have the individual elements, the algorithm starts merging them back together, but in a sorted order. It compares the elements in pairs and arranges them accordingly. This step is where the magic happens!
