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 ...
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 ...
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 ...
Hello Friends. I hope you are doing great. In this article, I will cover the nature of flow responsible for the changes in density. The nature of flows responsible for density change is known as compressible flows.
Fluid dynamics and thermodynamics combine for the theory of compressible flows. The compressible flow creates a relationship with the ideal gas. First, I will explain the stagnation state, speed of sound, and then the Mach number. This all comes under compressible flows. Then there come the static and stagnation fluid properties, shock waves, and variation of fluid properties in the case of regular and oblique waves. All of these are discussed in this article. So without wasting any time, let us start with the Stagnation property.
Stagnation Property
The definition of the sta ...
Several manufacturing processes for plastic manufacturers and metalworkers, like milling or casting, produce burrs. However, to guarantee the safety and quality of a component, one needs to ensure smooth edges that will not cause any problems in further processing or use of the item. Deburring and brushing machines are solutions to this issue. High-quality deburring technology from Germany can be integrated into casting and cutting machines, and to automatically produce flawless components.
Deburring and Brushing Machines from Germany
What are Burs, and How do They Develop? Burrs are unwanted protrusions of a material like metal or resin that can develop during processing. When picturing a component like a gear, it is easy to understand, th ...
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 ...
Every industrial facility that runs pumps eventually faces the same problem: mechanical seals fail. The question is not whether to deal with seal failures, but how much they are costing you — in downtime, in maintenance labor, in compliance risk, and in the consequences of fluid reaching places it should not.
The core question, then, is not whether magnetic drive pumps are good — they are, in the right context. The question is whether your specific application is one where their advantages matter enough to justify the switch.
What’s Actually Being Solved in Mechanical Seal Failure
Mechanical seal failure is one of the most consistently expensive maintenance problems in process engineering. Industry estimates put rotating equipment seal failure ...
Hi, my friends. Welcome to share a new tutorial in our ladder logic programming series. Today we will discuss counters in ladder logic programming using an expert’s view. So let’s wear the glasses of an expert in ladder logic programming and look deeply into counters, the types of counters, their variables and bits. In addition, techniques of using counters to solve a different kinds of problems that need counting. And without questions like every time, we will enjoy practicing programming and simulating all about counters. So with no further delay, let’s jump into our tutorial and nail that counters.
Counters in real life
Tell me, guys, if you can imagine an industrial project or machine that does not need to count parts, products, or processing cycles. Actually, in most cases in indust ...
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. ...
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 ...
