Sir I feel that in the part of the left you should have done à distinction And add another height because so it would be Pb+ Rho1gh1 +Rho2gh2 - Rho2gh2=0
the diagram at guage pressure is taken from the book RK Bansal which is incorrect.... the datum line should be taken at any of the liquid level!!! it can be either lighter or heavier liquid!!
Sir, in the LHS, some portion of that h1 height contains mercury also, then why is it only row1gh1??? row1 is the density of the first fluid while that portion contains mercury also
Here in second tube also having two different liquids one is 'water 'and other is mercury ,so h1 is the height which passing the water, it will exert a pressure on the mercury of height h2. Here layers are different that is water and mercury. That why only taking the heights of h1 and h2.
A pressure gauge consist of two cylindrical bulb B and C each of 10cm² cross section area ,which are connected by a U-tube with vertical limb each of .25cm² cross sectional are a red liquid specific gravity .9 is filled into C and clear water is filled into B. The surface of separation being in limb attach to C. find the displacement of surface when the pressure on surface of C,is greater than B by an amount equal to 1cm head of water..????
how did you take the height in the left limb as completely h1 eventhough we have two different fluids...since those two fluids have different densities and specific gravities how can we take the height as h1....and also we want to express the mercury level in terms of water which you didnt do.....can u expalin this
Sir for gauge pressure when we have to apply equilibrium then Above reference line we have mercury also why you have not added that could you please explain
@@JP-ys9fx atm pressure can never be zero, but here we are measuring gauge pressure. While measuring gauge pressure, the atmospheric pressure is taken as datum (i.e. gauge pressure is pressure above atm pressure)
Sir i'm confiused that how can u take hight h1 for two different fluid in first manometer ....i would like to tell you even in RK BANSAL BOOK hight h1 is considered for two different liquid but how?sir help me

If we made a water manometers
Will it gives energy automatically ??
Put wine or coolant or petrol in manometer
And fill water what is energy efficiency of manometer ???
Hlooo

Sir I feel that in the part of the left you should have done à distinction And add another height because so it would be Pb+ Rho1gh1 +Rho2gh2 - Rho2gh2=0
For gauge pressure the height h1 is having both liquid and mercury, why we didn't give separate height above datum AA?
sir what about the gap b/w lighter and heavier fluid in left side of diag. (a)
Amazing way of teaching
dint understand left one
how can we take height h1 when there are two different fluid
Sushma Mudbhari i think the diagram was not correct in the left, upto height h1 only first fluid should exist
Sushma Mudbhari t
the diagram at guage pressure is taken from the book RK Bansal which is incorrect.... the datum line should be taken at any of the liquid level!!! it can be either lighter or heavier liquid!!
wrong dia of left side
yes correct bro
Sir, Ur amazing, keep adding such videos , thank you sir😊
first acknowledging comment
Super👌 understanding with your explanation sir, I have problem with hydrolics in 4th sem
Thankyou, sir! best vid
So nice of you
Sir, in the LHS, some portion of that h1 height contains mercury also, then why is it only row1gh1??? row1 is the density of the first fluid while that portion contains mercury also
yes how?
That is the printing mistake in Bansal Book
sir .....you are superely in teaching ......
sir, please do it the vaccum pressure problem..
Sir, I confused in first u tube h1 how you take h1 as two different fluid...
Buy and Sell i'm also bro..
Here in second tube also having two different liquids one is 'water 'and other is mercury ,so h1 is the height which passing the water, it will exert a pressure on the mercury of height h2. Here layers are different that is water and mercury. That why only taking the heights of h1 and h2.
U r right they just following r k bansal sir book.. The reference line placement is not right in the book
A pressure gauge consist of two cylindrical bulb B and C each of 10cm² cross section area ,which are connected by a U-tube with vertical limb each of .25cm² cross sectional are a red liquid specific gravity .9 is filled into C and clear water is filled into B. The surface of separation being in limb attach to C. find the displacement of surface when the pressure on surface of C,is greater than B by an amount equal to 1cm head of water..????
Best teach sir
Thank you sir
Where we should take the reference line.....?
how did you take the height in the left limb as completely h1 eventhough we have two different fluids...since those two fluids have different densities and specific gravities how can we take the height as h1....and also we want to express the mercury level in terms of water which you didnt do.....can u expalin this
the diagram shown in video is wrong, upto height of (h1) there should be dotted line (light fluid).
Sir, R s khurmi (fluid mechanics) ky numericals ki videos banye
Very thank u sir good teaching
There are two different liquids in the left limb. I think we can't take h1 as the height for pressure 1.
yess bro
thank u so much veryuseful
Thank you sir it's very very helpful for my exam
Thnx sir ...
really great help!
sir,can u upload remaining portions also of fluid mechanics
Sir for gauge pressure when we have to apply equilibrium then Above reference line we have mercury also why you have not added that could you please explain
tq sir
All btect colleges same syllabus vuntundha
Sir jo physics k important formulay h us par ek video bany plzzz class 11 & 12
Ya Sure 👍
you have been making good videos ..but remember ONE mistake and students will lose confidence on your videos. this video is partially WRONG.
Can you elaborate the mistake in the video?
@Why so serious ? YES, then why uploader response and clear the issue
Are we neglecting the atm pressure on the right limb
Sir plz show the construction and working of MCLOED GAUGE
Sir left me height h1 Kaise hogi.mercury aur water dono hai Na???
thank you so much sir.
Sir,here why you haven't concluded the atmospheric pressure in the right limb.Also u have taken h1 for two different fluids
we consider atmospheric pressure as zero
@@JP-ys9fx atm pressure can never be zero, but here we are measuring gauge pressure. While measuring gauge pressure, the atmospheric pressure is taken as datum (i.e. gauge pressure is pressure above atm pressure)
Left diagram is wrong one.....show line A-A appropriately
nice sir!
sir ji left limb is wrong one
great help
You are most welcome.
sir can u tell me types of Warburg constant volume manomete
sir thank u sooo much
why is it u are taking h1 for measuring pressure whilst we have two different liquids
Sir dono pressure ko ......equal Kyu kiye plzzzz reply
Sir i'm confiused that how can u take hight h1 for two different fluid in first manometer ....i would like to tell you even in RK BANSAL BOOK hight h1 is considered for two different liquid but how?sir help me
Lower dense liquid will float.So Mercury more denser than water so it like a sink
Tq very much sir
Thank you for this vidio sir
We are always happy to help you!

Sir please explain me the numerical problem related to manometer
How many don't under stand this qus like heare
How I can see the private video 👆
sir, please write the video number in order.
I will no under stand
Left diagram is incorrect there should be only 1 liquid in h1
Wrong solve kiya h sir aapne......h1 hight me left me 2 fluid hai
we are very happy
surya surya, No we are not!
Sir in 219 videos many videos is in pravicy how we Will watch sir make those are public

sir ek question. mera v hai..uska ans. aap mujhe mere Gmail pe bjh dijieaga...plzzzz
The given h1 in guage pressure is wrong
Nice one
Yes there is mistake in first equation
Why u shaped tube is used in this
Other than |_| like this is not used

Diagram a is wrong
Sir itz little bit confusing...😢
The concept is not completely correct
hi
not effecient
partially wrong
good
Make a bit confused
Bhadi
Op bhai
Maighai
Rk bansal ke diagrams haaaa
ur figur is wrong ,position of datum line is wrong,(also in bansal textbook),

It is wrong
bahut bol kar diya yaar 😅
This is text book copy... no clear explanation of concept... better refer to text book rather than this video
+1 Sub :)
Wrong figure sir
First of all your diagram A is wrong
Couldn’t underatnd much
Hindi nahi atti kya
Wzste
Galt hai
This video is wrong
Sir apko padhane nahi ata hai
sorry Wrong explanation...
tq sir
Thank you sir
Thank u sir
thanks you sir
thanku sir
