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 ...
Metal fabrication
refers to the manufacturing of sheet metal and other types of metal to fit different shapes.
The metal fabrication industry is vital to a wide range of industries. That’s due to the reliance on metal fabrication for vehicle parts, train tracks, building equipment, electrical devices, etc. A metal fabrication shop has various pieces of equipment needed to design and fabricate a myriad of metals. So, what, then, is custom fabrication?
What is Custom Metal Fabrication?
Custom metal fabrication refers to the production or fabrication of a range of metals to meet unique specifications. Custom metal fabrication projects are carried out for a specific purpose. It involves cutting, bending, rolling, or joining metal to create custom complex shapes based on specific req ...
3D printing is one of the most promising technologies in recent breakthroughs. One of the most inherent benefits of 3D printing is additive innovation; it opens up an entirely new way of creating products and provides numerous benefits over traditional fabrication techniques.
Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project?
Affordability
One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of ...
I still remember the first time I had to choose between a strain gauge and a torque sensor. It was a cramped motor lab. Old bench. Coffee gone cold. The project manager wanted answers by Friday. On paper the choice looked simple. In the real world it never is. Every project has its own personality. Speed. Budget. Accuracy. Abuse level. And usually a deadline that doesn’t care about any of that.
If you have spent time around test stands and factory motors you know this dilemma well. Torque measurement sounds straightforward until you actually have to do it. That is when questions start piling up. How accurate do we really need to be. Will this thing survive vibration. Can we install it without tearing the whole setup apart. And the big one. Will it still read the same after six months of h ...
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 ...
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 ...
Flow visualization widely uses Computational Fluid Dynamics (CFD) and physical experiments. So following are the types of patterns that can be visualized computationally and experimentally. So without wasting any time, let us start.
Streamlines and Streamtubes
There are two patterns. I will first explain the streamlines. So the definition of streamlines is as follows:
A streamline is a curve that is tangent everywhere to the instantaneous local velocity vector.
You might not understand the definition by reading it, so just for your ease, let me explain to you in few key points:
A streamline defines fluid’s motion throughout the flow field.
A streamline acts as an indicator of the instantaneous direction of motion of the fluid. To explain this situation, let me exemplify it with an ex ...
Hello friend. In this article, I will cover essential points related to fluid kinematics, i.e., what fluid kinematics is and how the motion of the fluids can be explained without describing the forces acting on them. Further, I will explain Lagrangian and Euler about the motion of fluid and a lot more. So buckle up, and let’s start.
What is Fluid kinematics?
The definition of fluid kinematics is as follows:
Fluid kinematics is related to fluid motion without considering the forces responsible for the motion.
The following are some essential key points related to fluid kinematics:
The nature of fluid motion is categorized into two types: Lagrangian Euler.
I will extensively explain both types in upcoming topics.
The acceleration, velocity ...
Hello Friends. I hope you are doing great. Here I am with another exciting topic of fluid mechanics, i.e. flow over bodies. In this article, I will explain the flow of fluids, the flow rate, their nature, the flow in pipes and much more. Fluid mechanics is all related to the fluid and its nature. I will discuss the forces that are on the body that is immersed in a fluid and the flow that is over the body. As the title shows, the main emphasis will be on the lift and drag forces. Moreover, the external and the internal flow will also be discussed in this article. And I am sure that you will enjoy reading this article. So without wasting any time, let us start.
I will start with an introduction to fluid flows.
Introduction
In this article, our focus will be the fluid flow over the bodies ...
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 ...
