It is one of the most critical topics whenever. It is related to the resistance a fluid faces in motion. A fluid exerts a force on a body in a different direction. Now the main question is, what is drag? And what do we know about it?
What is Drag?
The definition of drag is as follows:
The force exerted on a flowing fluid in the direction of fluid flow is called drag.
Some of the essential key points related to the drag are as follows:
In order to elaborate on the drag force through an example. The body is attached to calibrated spring, and it is used to measure the displacement in the direction of flow.
The drag balances are one of those devices that are commonly used to measure the drag force.
It is not wrong to say that the drag force is much similar to the frictional force. ...
It’s 2019, and everyone’s wondering if PBNs or Private Blog Networks are still worth building. Some would say yes, while others say no. Looking back at how it started (who can forget how Google penalized two public blog network and made them a cautionary tale?), there will always be proponents and opponents of this SEO technique.
PBNs gathered steam in 2014, but people have been searching about them since 2005 based on Google Trends. It is highly likely that it has been used by many SEOs since then or even earlier.
When it became the go-to strategy for grey hat SEO, the conversation went from “maybe” to “how to use PBNs effectively”. In fact, deciding which is the best solution for hosting became a critical part of building PBNs. After all, the c ...
Welcome to the next tutorial on our raspberry pi four python programming. In the previous article, we built a system that recognizes when two people are in physical contact using OpenCV and a Raspberry Pi 4. We used the weights from the YOLO version 3 Object Recognition Algorithm to implement the Deep Neural Networks part. Regarding image processing, the Raspberry Pi consistently comes out on top compared to other controllers. A facial recognition program was among the earlier attempts to use Raspberry Pi for sophisticated picture processing. In today's world of cutting-edge technology, digital image processing has expanded rapidly to become an integral feature of many portable electronic gadgets.
Digital image processing is widely used for such t ...
Outsourcing is a relatively new form of organizing work. Yet, nowadays it’s probably the most effective and profitable way to have your project done. No wonder businesses all over the world prefer it over the traditional methods. But what is outsourcing and how it works? What are the advantages? What trends does this sphere have today?
Outsourcing Basics
Outsourcing works in a really simple way. A company needs a part of the project done, but they don’t have enough employees to finish it in time. So, they hire specialized outsourcing teams that provide professional assistance in all the needed aspects.
That doesn’t mean it’s limited to being some kind of assistance service, though. Remote dedicated teams can work on a separate part of an already existing project, or even develop a produc ...
Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at Reasons You Should Consider Buying An iMac. Are you on the verge of buying a new computer? If so, you should most definitely think about investing in a computer made by Apple. The company is best known for its smartphones, but their computers are pretty amazing as well. The company offers the Macbook and the iMac. If you’re looking for a desktop, you’ll definitely want to think about investing in an iMac. Why? You’ll find out in the guide below.
Great Software
First and foremost, you should know that Apple makes some of the best software on the planet. Apple computers do not have the versatility of Windows computers. Your software options will be limi ...
To understand this section, we must know a little history. The history of the development of printed circuits is not as old as that of the industrial revolution, around 1950 is when the first PCBs began to be commercialized, however, in the early 1900s it was when the first attempts at PCB designs emerged.
The human being had the need to have electrical equipment that had a reduced size, before this the search began to replace the complex and extensive cable connections with electronic components.
It was on March 2, 1925, that Charles Ducas first filed a patent that included creating an electrical path directly on an insulating surface.
Technology has advanced and electronics are not left behind, as can be seen in the previous image, the first pr ...
Hello friends, I hope you all are fine and having fun with your lives. In today's post, we are gonna have a look at How to use C# ArrayList. I am gonna explain it in detail what is C# ArrayList and how to use C# ArrayList. But before going into the details of today's tutorial, you must first have a look at my previous tutorial which is How to use C# Array??? because C# ArrayList is quite similar to C# Array.
I am gonna use the same project which we have designed in our first lecture on C# named as Introduction to C# Windows Forms. So, you should also use the same project and as we know this project has one Button and one Text box. Just a recall that I have changed the Text of the button to Click Here and the name of the button to ClickHere. Simila ...
Update: Here are the latest versions of this library: Arduino Nano Library for Proteus V3.0 and Arduino Nano Library for Proteus V2.0.
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am going to share a new Arduino Nano Library for Proteus. Arduino Nano is also a microcontroller board just like Arduino UNO but the advantage of Arduino Nano over Arduino UNO is its small size.Arduino Nano is quite small in size and hence can be used in such projects where we need to use smaller PCBs. For example, I once worked on a project in which I needed to design a test cricket bat.In that project, I used IMU along with Arduino Nano and placed the complete kit over the bat. As I need to place the electronic kit over the bat so it has to be quite small, that's ...
Hello everyone, I hope you all are fine and having fun with your lives. Today, I am going to share a semester project which is named as Automatic Street Light Project. I have designed this project in Proteus ISIS and the simulation is also given below for download. Btw this was my first project during my engineering course. :D I had really enjoyed while working on this project as I was new to electronics then.
This project is about Automatic Street Light. You must have examined on your streets that the street lights turn ON at night while they turn OFF in the day. When I was a child then I think that someone turns ON the switch in the day and then turns it OFF at night but that's really not the case. :P
In fact, these lights are automatic and have ...
In the past, graphic designers had limited choice of graphic design tools. There were only 3-5 great design tools for professional work. This has all changed with free and open-source platforms making it easy to design what you want, wherever you want it. Also, many of these tools are cross-platform too, meaning you can whip up some quick designs on your Android or iOS device. Because the sheer number of available tools makes it harder to pick the best one, we are going to look at 5 great ones that you should be using right now.
Adobe Illustrator
Almost all designers agree that Adobe Illustrator is the best tool for creating vector graphics. You can use the software to create artwork, logos, infographics, artwork, icons, and pretty much anything ...
