Thank you 💖

Thank you so much! The playlist reminds me of the time that I'm still mentally stable 😌😂🥲
Thank you 😊😊😊 its nostalgic.
My high school years....miss those days. Life was simple and complicated but fun😊
My childhood 😢 I miss those days where you could wake up and know nothing is gonna happen, relax, watch CZcams, have fun, and just be excited for the next day, but ever since COVID that has not been happening at all.😢
It’s been 14 yrs and still songs hit me hard 😢
This playlist screams childhood for me, seriously.
One of my best childhood years. The friends, school, street I lived on, and of course being a kid. I was devastated when I had to leave the former three in 2011.
I am born in 2012 but I still know all these songs😅
Old songs brings back good memorys❤
I got ricked rolled by a add :(
nice
Same 😩
With 2 ads 😭
@@_julie_01 R.I.P 🥲
Same 💀💀
i born in 2007 so i know all this songs, and this just hit harder. I love been a 2000's kids
You were never a 2000s kid lol.
@@daxamite2111He was 2 in 2009.
I was really young when it was this time still am young but 2000s songs make me happy 😊
Nostalgia hits hard
old song ,,,bring back memories ,how i miss those days
the best year of my life. 2009-2012 3rd year Highschool to 2nd year college
best throwbacks ever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
😍
What a wonderful playlists!
i was born in years 2005 but this music is so Nostalgic to hear.
True and me too
@@yevgenymillkovich85 cool
I LOVE THIS PLAYLIST!!!!!!!!!!!! THANK YOU
I miss college days 😔 thank you for this playlists❤
Ah, zaman lulus kuliah.. me after college graduations. Starting my new life as a worker. Now, mom of a tenager. Time flies. Love the vibes. ❤
Oldies but goodies 🤩
YEAA YEAA
this hits so hard like fr
I love this play list😍
This is a perfect playlist❤ love itt
ilove this music era so much😢
Thank youu 💙🎼
98 babies let's gather here🥺❤️
🙋🏻♀️
I love this playlist ^_^
old but gold
Good playlist 🔥❤️
Highschool feels :D :D :D Those were some of the best days of our youth! :D :D :D
The measurement of static, velocity, and total pressure across air ducts is an essential practice in the fields of heating, ventilation, and air conditioning, as well as in various industrial processes. This practice involves the assessment of different types of pressures within ductwork to ensure that air distribution systems operate correctly and efficiently. Understanding the theory, concepts, and working principles behind these measurements is critical for engineers, technicians, and facilities managers who are responsible for maintaining air quality, comfort, and operational efficiency in buildings and industrial settings.
Static Pressure in air ducts corresponds to the pressure exerted by the air on the duct walls when the air is not moving. It is a critical aspect of system design because static pressure influences how air flows through ducts, impacts fan performance, and affects the overall balance of the HVAC system. Higher static pressures may indicate obstructions or poor duct design, leading to energy inefficiencies. When measuring static pressure, the common instruments include simple U-tube manometers, inclined manometers, or advanced digital pressure transducers.
Velocity Pressure represents the air's kinetic energy within the duct and is related to the air's velocity. The velocity pressure is essential for calculating the actual speed at which the air moves through the duct system. This speed directly affects the volume of air delivered to various parts of a building or process, dictating the performance of the air handling system. Typically, the velocity pressure is measured using instruments like Pitot tubes, anemometers, or velocity probes that, when inserted into the duct stream, can measure the dynamic pressure changes caused by airflow.
Total Pressure is the sum of static and velocity pressures and is the total energy within the air stream. It reflects the complete energy potential of the moving air and can be measured by bringing the air to a total, isentropic stop. The measurement of total pressure gives insight into the capacity of fans and air handlers in the system and can pinpoint areas where the system might be underperforming or overperforming. This is crucial for systems where air balance and precise airflow rates are essential.
The theory behind these measurements often relates to the principles of Bernoulli's principle, which posits that an increase in fluid velocity leads to a drop in pressure and potential energy within a flow field. This is central to the working methods of devices used to measure static, velocity, and total pressure in air duct systems.
The working principles of these measurements involve tools such as manometers and Pitot tubes. The manometer, commonly a U-shaped tube filled with a liquid, compares atmospheric pressure with the pressure within the duct. The differential in liquid columns within the manometer equates to the static pressure inside the duct. On the other hand, the Pitot tube measures the impact pressure (total pressure) of the air, and with a separate port, measures the static pressure. The velocity pressure is then determined by the difference between the total pressure and static pressure, utilizing the relationship governed by Bernoulli's equation.
In the world of applications, these pressure measurements are indispensable. In HVAC systems, accurate pressure readings enable engineers to design ductwork that provides the right amounts of conditioned air to different building zones. It ensures systems are neither overworked (leading to unnecessary energy consumption) nor underworked (causing discomfort or unmet process requirements). In industrial settings, controlled airflow is crucial for maintaining desired environmental conditions, removing contaminants, or controlling moisture and temperature levels critical to production processes.
Besides their practical applications in HVAC systems and industrial processes, pressure measurements in air ducts serve important roles in research and development. Detailed knowledge of airflow characteristics can lead to the development of more efficient ductwork designs and improved air handler systems. In high-precision industries like semiconductor manufacturing or in settings like hospital operating rooms, the control of air pressure and flow is vital for maintaining sterile environments.
In environmental applications, understanding the behavior of air pressures is crucial for predicting and controlling pollution dispersion in the atmosphere. In aviation, automotive, and marine industries, exploring airflow characteristics around structures improves design efficiency and performance.
Overall, measuring static, velocity, and total pressures across air ducts is a multifaceted endeavor that relies on robust scientific theory, precision instruments, and it underpins the operation of a vast array of systems that impact comfort, safety, efficiency, and technological progress.
Im obbsesed with your playlists
Me born 2011 knowing all these songs: YESSSS
I'm born in 2012 and I now this song
I’m born in 2010 and know all these songs
ilove this playlist
This playlist is lit
THE FIRST ONE IS MY NOSTALGIC SONG WAA
Amazing
I was born in 2011 and in still know all the songs❤️
I was even born yet but I know all the songs
Its song when i was junior hight school. Ceasing and get ceased by, what a memory
Miss those days 2009😔🥺
All my favourite 🤭
I was 14 in 2009 and remember me and bieber were born the same year..he was my celebrity crush
Not me eating noodles at 1:00am bc I’m bored
It be like that sometimes 🤣❤️
Me too
omg!!😮😮😍😍😍😍
Suddenly miss my teenager era
16 to even 9 we all have hte same childhood songs?
Omg those songs are totally new to me, never heart those song before😮😮
Wait seriously!?
No way
Me too
I used to dislike Justin Bieber, but now i just realized he is this good
Pumped up kicks not being here is a crime
yasss
great
early!!!
2009 was the most memorable summer 16 years old an plenty of chicks to go around
God, I feel old
When I first see my friend I fell so good that I have a kind friend but now I have no friends 😔😔😔💔💔

Stop cause my jaw dropped when i heard Party in the USA
I feel very sad I really want to cry everything like hell right now why 😣😣💔💔
I was born this year man i I know every word of these songs😅😂
Ayyy! Same!
2023 🎉
Maybe add stressed out? The title made me think it was in it.
Me 2009 liners
I want to know want is famous song then

Hi
My 1st grade years💔💔💔💔omgg
Wait what does omfg mean 👁🗨
What happened to the gift of a friend?
you have 2010s?
I'm actually born in 2009 lol
You're 13 HAHAHA i can't believe you guys are on youtube now

@@yuh2367 we were born on the same year
@@yuh2367 I'm already in high school
2nd year
Omg samee! But this was the music I listened too 😍
💕💕💕💕💕🙂🙃🙂🙃🙂🙃🙂🪩🪩🪩
aaaaaaa!!! add
Why do people like 2009?
BELIVE IN JESUS CHRIST AND REAPENT FOR SINS MY BROTHERS AND SISTERS IN CHRIST IN JESUS NAME AMEN✝️❤️😍🙏😇
