You are the MVP. It's my first week in thermodynamics and I was about to drop out because I didn't understand a lick of it and now im just cruising by the homework problems. Thank you for this valuable free content!
Dear Sir............Example Problem : One hydraulic cylinder, the end is connected to the Threaded rod so that it can be rotated. Cylinders with a bore size of 18 mm, 10 mm rod and a stroke of 300 mm single acting in a condition that is filled with oil. If the cylinder is rotated 10 mm. a. How to calculate it b. What is the gauge pressure
Why we cannot use a dam like a barometer which gives electricity without flow of water outside so we can provide electricity even if there no enough water in dam
Pls is the: A. The density of the gas is less than the density of air. B. The density of the gas is greater than the density of air. C. The pressure of the gas is less than atmospheric pressure. D. The pressure of the gas is greater than atmospheric pressure. Thanks need answ. nowww
No, It doesn't act like that. Forces just become unbalanced. If it was a pure vacuum then the whole liquid is shifted to the other side because atmospheric pressure is 10^5 Pa and Vacuum pressure is 0. Hope it helps!!
So if the pressure of the gas is removed, the mercury would mount on the right side to the same level as the left side,, does this mean that gravity is pushing and pulling at the same time? In other words why does gravity need to find a level?
So if you just use the height difference of 600mmHg and convert to Pa, you calculate a slightly different value: 181,317 Pa. Can you reconcile? Especially given your video here: th-cam.com/video/8P5NlpxGT7Y/w-d-xo.html Same for the second example: 47,995.92 Pa

bro i a always impressed how this guy can explain a whole chapter in a few minutes . wish my lecturers was that simple
You are the MVP. It's my first week in thermodynamics and I was about to drop out because I didn't understand a lick of it and now im just cruising by the homework problems. Thank you for this valuable free content!
Bro you don't understand how much this helped me. Thank you ever so much!
This few minutes is million times better than 2hrs I spent to learn this in class. Thanks bro
Very helpful. This video clarify my all misconceptions. Thank you very much Sir.
i just have no words ,,,,,,,,,.......its best ..excellent i understood everything
Thanks so much for the video. Helped unlocked something that wasn't clicking. Much appreciated!
The most advanced tutor in the world.
This is very helpful for my Thermodynamics module for Engineering. 🙏
my physics exam is tomorrow, I full understood about open tube manometer calculations
thankyou bro.
thank you sm sir,you saved my grades(I have physics exam tomorrow)
Am going for a test... If it comes and I have smashed it... I will give you a five star rating
This video is thousand times better than my professor's explainstion
thanks dear teacher i always watch your videos whether it's physics or math thanks again keep doing
banger video my guy
you are a lifesaver
No one:
Me before he even says it: in this video..
Thank you soo much
Thanks mate this video saved me 40 bucks!!!!!
How? I wanna learn
How? I wana learn
@@edpagan5421 he usually gives Joseph in our class 40bucks to cheat from him. now that he learned from the video he doesn't have to pay the 40 bucks
thank you SO much for this video!!
thank you priiiii. this thing really helpss
Thank you!💜
Thanksss alot💕

a. How to calculate it
b. What is the gauge pressure
in the first number , what if the liquid is changed with water ? what is the solution and what parameters should be changed ? thx
i dont understand the gauge pressure part. 6:21
Thank you sir.
Limitations of Peizometer : Gas pressure can not be measured because gas can not form a free surface
Thanks
this is dope
THANK YOUUUUUUUUU
Can you please vividly explain Pl=Pr
When we neglect the atmospheres pressure?
Whenever we can!
when it's a closed tube. as long as air can access the tube you have to consider the atmospheric pressure
Menelantarkan
A doubt: can't I take pressure in atm itself?? That's a pretty simple number---1
i have understood even compared to when am in class🙄🙄
how can i know one of them are more pressure?without graphs
SALAMAT!
For the u-tube manometer you didn't convert cm to m why??
Why we cannot use a dam like a barometer which gives electricity without flow of water outside so we can provide electricity even if there no enough water in dam
you are beast bro!!!
Khan Academy my ass ! This is the best channel!
Pls is the:
A. The density of the gas is less than the density of air. B. The density of the gas is greater than the density of air. C. The pressure of the gas is less than atmospheric pressure. D. The pressure of the gas is greater than atmospheric pressure.
Thanks need answ. nowww
what have to find
where does 9.8 come from?
Gravitational acceleration 9.8 m/s^2 ρ(g)h
So if the gas pressure is less than the atm then it acts like a vacuum
No, It doesn't act like that. Forces just become unbalanced. If it was a pure vacuum then the whole liquid is shifted to the other side because atmospheric pressure is 10^5 Pa and Vacuum pressure is 0. Hope it helps!!
Thx
what about the 60 cm height
So if the pressure of the gas is removed, the mercury would mount on the right side to the same level as the left side,, does this mean that gravity is pushing and pulling at the same time? In other words why does gravity need to find a level?
because gravity is a downward force acted upon things so we need to consider it.
I don’t understand 😭 i might fail physics help anyone pls
What if I’m not given the height of mercury?
solve for "h" in the equation if other values are given.
*G O A T*
Hero!

WTF
errrrrr this just confused me even more. god damn it :(
Imposible
Thankyou
