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 ...
We learned in the previous tutorial how to connect a joystick to a Raspberry Pi 4 using an mcp3008 and an op-amp IC, the LM324A. For each of the interface methods we studied, we created a python script allowing us to interact with the circuit. This tutorial will show you how to connect a 4-channel relay module with a Raspberry Pi to carry out switching.
A relay's primary function is to allow a circuit to be controlled by a weak signal. High-current applications necessitate relays to separate the low-voltage control circuit from the high-power driving circuits. Because of this, understanding it is crucial for those interested in industrial or household automation.
If you've been tinkering with a raspberry pi for a while, consider the various ways ...
Civil engineers have more power on the desktop—and in the cloud—than ever before. The 2025 generation of design platforms blends Building Information Modeling (BIM), traditional CAD drafting, GIS context, and AI‑assisted automation into one fast‑moving toolkit. Below is a plain‑language look at the best civil design software choices this year, what they do well, and how to pick the right match for your team.
What Makes Great Civil Design Software in 2025?
Connected BIM + CAD – Models, drawings, and data stay in sync across disciplines.
Open standards – Support for IFC 4, SAF, LandXML, and DWG keeps projects portable.
AI‑driven speed‑ups – Auto-classification, code checks, and alignment suggestions trim hours of manual work, such as in transportation engineering services
in Austin, wh ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna Create a New Controller in ASP.NET MVC. It's 6th tutorial in our ASP.Net MVC series. We have already had a look at basic Introduction to Controllers in ASP.NET MVC and they are used to communicate between Views & Models.
So, now we are gonna have a look at How to Create a New Controller in ASP.NET MVC. It's a very quick tutorial, as there's not much to do with Controller rite now, we will just create one. So, let's get started with it:
Create a New Controller in ASP.NET MVC
In order to Create a New Controller in ASP.NET MVC, you have to right click on the Controllers folder in Solution Explorer.
Now click on the Add and then click on Controllers as shown in ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about Interfacing of LCD with 8051 Microcontroller. In my previous post, we have seen How to do Serial Communication with 8051 Microcontroller, which was quite a basic tutorial and doesn't need much hardware attached to it. Now today we are gonna have a look at Interfacing of LCD with 8051 Microcontroller. LCD is always the basic step towards learning embedded as it serves as a great debugging tool for engineering projects.
LCD is also used almost in every Engineering Project for displaying different values. For example, if you have used the ATM machine, which you must have, then you have seen an LCD there displaying the options to select. Obviously that's quite a ...
What raw materials that your PCB is comprised of?When you cannot answer this question clearly, please continue reading. When you are interested in PCB raw material testing, you better keep reading. When you are in doubt about the quality of the JLCPCB board material, you must continue reading. All corporations that value products and services paramount importance. The raw material is life for a product. This is especially true for PCB production. How JLCPCB controls the level of raw materials quality? The testing videos tell the truth.
JLCPCB never take undue advantage of Non-A grade board
Global PCB raw material costs are rising, JLCPCB never takes undue advantage of Non-A grade board. Last year the whole PCB manufacturing industry faced raw mat ...
Hello, welcome back with another PCB tutorial and in today tutorial I am going to discuss “What is Future of PCB?” Now, you will be pretty aware of the Printed circuit board.
Since the invention of PCB, there are different changes and evolvement happened in PCB and its evolvement make it advanced. Now PCBs are available in different shapes and hardly resemble their first invention. They are not just changing shape, but their efficiency rate is much higher than before. The manufacturing process and design of software make it more productive and cost-effective.
Now consumer demand is growing within passing time and so must PCBs. PCB is the base of all electronic devices. There is no doubt that the PCB maker feels intense pressure on developmen ...
Hello Learner! Welcome to another exciting experiment at The Engineering Projects. We hope you are having a great day. In this lecture, we'll seek information about the Boost Converter Circuit from scratch to result in quick and easy steps. So, if you don't know about the experiment then don't worry because every Expert was once a Beginner. We'll talk about the following topics:
What is IRFZ44N MOSFET Boost Converter?
What is the brief introduction of components of circuit?
How can we implement the IRFZ44N MOSFET to design circuit of Boost Converter?
You will know some useful information about the topic in the DID YOU KNOW sections.
IRFZ44N MOSFET Boost Converter
During the experimentation of electronic circuits, we often face the situation ...
Hello friends, hope you all are fine and having fun with your lives. Today's tutorial is about speed control of DC Motor using PIC Microcontroller. I haven't written this tutorial by myself. Instead this tutorial is written by one of my very good friend Salah Dahouathi. We had an interaction through his awesome Facebook group Let's Think Binary and I would suggest you guys to join it as well, because he posted many projects in his group. So, after having a look at his work, I asked him to write for our blog which he gladly accepted and here's his first post. :) I hope you guys are gonna enjoy this one and will get knowledge out of it. So let's get started with this speed control of DC Motor using PIC Microcontroller tutorial.
Many applications in ...
Hello friends, a few days ago I posted an Ultrasonic Sensor Library for Proteus, using which one can easily simulate ultrasonic sensor in Proteus. The post was highly praised by the reader and I have received quite good feedback from the followers. So, I thought of sharing some more examples related to it so that users can get a complete understanding of how to use Ultrasonic sensors in Proteus. Today, we are gonna have a look on different Ultrasonic Sensor Simulation in Proteus. If you haven't read the previous post then first have a look at it because without the installation of Ultrasonic Sensor Library in Proteus, you won't be able to use these examples. Ultrasonic Sensor is used widely in Embedded Systems.Today, I am gonna share three examples of Ultrasonic Sensor Simulation in Proteu ...
