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. ...
The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start.
Pressure
The definition of pressure according to fluid mechanics is as follows:
Pressure is the normal force applied by a fluid per unit area.
Unit of Pressure
The units of pressure Pascal is too small to deal with in practical cases. For instance,
Kilopascal: 1kPa=103Pa
Mega Pascal: 1MPa=106Pa
The three common pressure units used are standard atmosphere ba ...
3D Printer is an electronic machine that uses digital data to generate physical 3D models through successive layer printing. A 3D printer can make an object's physical model either scanned by a 3D scanner or designed using a CAD program. 3D Printing is an additive manufacturing technique where successive material layers create a three-dimensional object (Rapid Prototyping). The 3D printing concept is fascinating. Who is not excited about 3D printing? The use of inkjet technology in creating 3D models is a revolutionary method that costs less and saves time by eliminating the designing need for separate model parts. One can use a 3D printer to make a complete model in just a single process.
Several industries use 3D Printers in printing various out ...
Product designers nowadays have access to various technologies for creating multiple prototypes. These include traditional methods such as pen-and-paper sketching and cutting foam blocks, as well as more modern technologies such as 3D printing and CNC machining service.
However, today we will focus on the additive manufacturing technique and what you should look for during your search. Numerous businesses embrace the technology by delegating tasks to professional 3D printing services.
In the globally competitive environment, adding a supply partner to the company's value chain is the way to go because the technology is capital-intensive to implement. To help more businesses adopt the technology, we've created a simple guide to help them select the ...
By using CNC-machined parts for your next engineering project, you can ensure precision, quality, and speed. So, let us take a look at three options for creating custom parts.
What Is CNC Machining?
Before we look at the three options available to you, it is worth briefly explaining what CNC machining is. CNC machining is short for Computer Numerical Control. It is a modern manufacturing method that involves the use of computer-controlled machinery to make custom parts.
The process begins with creating a CAD design
of the part you want to make. The design is then translated into g-code
and fed into the item of CNC machinery.
The machine then simply gets to work at creating your design with the utmost precision and consistency. The types of CNC machines
range widely – from mil ...
Milling is a machining process that can create detailed or complex shapes from metal, plastic, or other materials. The CNC milling process involves using a computer to control the motion of a rotary cutter that removes material from a workpiece. This article will discuss things you need to know about the CNC milling process.
What is CNC milling, and what are its uses?
CNC milling is a machining process that uses computer numerical control (CNC) to cut materials precisely. It can produce complex shapes with high accuracy and repeatability from metal, plastic, or other materials. It is used for many applications, including prototyping, manufacturing parts, making moulds and dies, creating fixtures for production lines, producing 3D sculptures and m ...
Step into the world of precision engineering—where custom CNC machined parts transform raw materials into the sinews and bones of your next big project. Like a tailor crafting a bespoke suit, CNC machining offers an unparalleled fit for your specific requirements.
The prospect of holding your idea in your hands, not just on paper, is the realm where imagination meets implementation. But what options lie at your fingertips? Let's explore the paths to turning those digital blueprints into tangible assets.
Materializing Visions: The Alloy of Choice
Before the whirring of machines begins, your quest starts with choosing the right material—a decision as critical as selecting the foundation for a skyscraper. Each material whispers its own strengths and secrets, waiting to align with your proj ...
The first law of thermodynamics is also known as the Conservation of energy Principle. I will explain what is energy principle is and the following are some important points of the Energy Principle:
The energy principle can be described as the following equation:
Ein-Eout=∆E
I will exemplify the energy equation through a simple example. For instance, the rock fell from the cliff and while falling from the cliff the rock gained speed and the speed doubled while coming down. The potential energy is converted into kinetic energy as the rock is falling from height. Here the air resistance is negligible here. All these factors confirm the conservation of energy principle.
One of the simple examples of the Conservation of Energy Principle in our daily life is the man who has a lot of ...
In this article, I will explain the differential equations of fluid motion, i.e., conservation of mass (the continuity equation. So without wasting any time, let us start.
What is differential Analysis?
As a part of this article, it is essential to know what differential analysis is and how we can apply it to explain continuity and Naiver Stroke’s theorem.
Some of the essential key points related to the differential analysis are as follows:
Differential analysis is the application of a differential equation of fluid motion to any or every point in the flow field over a region called the Flow Domain.
Some readers might confuse the word differential with the small control volumes piled up on each other in the flow field.
Whenever the size of the control volume crosses the limit a ...
Hi, my friends and welcome back. I am happy to meet you again with a new tutorial of our PLC ladder logic programming series tutorials. Today we will complete what we started the last tutorial on the Elevator control project. We have a bunch of duties to complete together today. So let’s save time and jump into work immediately.
Project description:
Figure one shows the details that might help me describe the project between our hands. We have an elevator car that travels up and down and can stop on one of four floors based on the passengers’ requests. We have 6 push buttons on the wall next to the elevator door that can send requests to call the elevator. In addition, there is a control panel inside the elevator cabinet in which there are push buttons to request stations to reach floors ...
