HTML-код
- Опубликовано: 12 ноя 2017
- This physics video tutorial provides a basic introduction into U Tube Manometers with two liquids. It explains how to calculate the height of the oil column as well as the height of the water. In addition, it explains how to calculate the density of an unknown fluid using a u-tube manometer. This video contains 3 practice problems for you to work on.

You are divine sir, I always enjoy your tutors
The explanation is AMAZING
Thank You
I had an exam today and you helped me passing it, thank you so much for your amazing videos , your teaching skills are amazing and you are intelligent as well. God bless you ❤️❤️
Thank god for your channel, I just barely managed to write the test thanks to you.
You certainly made physics easier with this amazing vedios, Thanks a lot👍
Most helpful video to explain this equation, amazing man !
and now I am ready for my final. best explanation of the topic i found. Thank you.
YOU ARE THE BEST! Thank you so much!!
thanks for your efforts
Thnx so much for this
Amazing teaching, sir.
I still have a question ; what happens when the U tube Manometer contains three or more liquids? How to calculate the height or density of one of the liquids.
thanks you helped me understand this :)
Thanks for your time
this is so much more understandable than my ChE professor makes it.
You are reliable ♥️
Appreciate you
Thank you!!!
Thankyou so much.
Sir you must not neglect, it must be dimensionally consistent
nah it just cancels
@TamannaAdrina-oj8fe nah im indian and maolito sounds hispanic
since you're using the heights in cm, shouldn't they be converted to m for correct densities to be found in kg/m³
Yes it should be
that is what i need, tqq😍
it doesn't matter because it crosses out in the end. but you can convert if you like. The answer will remain the same
Thank you so much ❤
Thanks man
We usually equalize the pressure on a same liquid
So in the first interface, can we do that , since there are 2 different liquids
Thank you so much
Thank you so much sir ❤
I feel learned
i have a question 🤚🏻 for #2 as the height of water above the reference leveldecreases, the specific gravity of oil decreases as well??
Thanks...!!!
Thank you Sir. Really a very helpful video
You need to convert cm to m first with these formulas. The density is measured in kg/m3, you can't now do the calculations with the height in cm, the SI base units won't make sense. Either convert kg/m3 to kg/cm3 or cm to m. cm to m is much easier.
You will still get the same value if you convert it, try it🤝
how can we cancel out Patm if it acts on different heights, on the right side it will be stronger than on the left since the height of vertical air block is bigger, the difference will be very small but there will be difference, on the left side Patm=air density*g*h, and on the right side Patm=air density*g*(h+d), d being the height difference between 2 sides
Thank you . My books explanation is like 💩. But you helped me . Hope this type of ques come in my exam ✌️💯
😅😅😅
Thanks❤❤
Nice 👍
When do you convert liquids to become uniform liquid
can someone tell me why isnt this taken into account when calculating the pressure transmission through a fluid
What if there's an ratio included inorder for to find h2???
Thankyou
this is my favourite video to come back and watch when im fried
Final is around a few hours and i'm watching this
hopefully you did well, just took an exam and the U tube was on it.
What is that app
this is the probable problem which is gonna come in tomorrow's exam of 9702 feb march 33, thank you so much sir, this is gonna get me full marks
How well did you do on that exam
@@sausage563 ended up getting 29/40,
I know its low but I got an overall A
@@busyinverse4300 i just got a 7/10 on a quiz for this topic today, i guess it's just hard
@@sausage563 I know right!
during cambridge exams, when luckily this same topic came, I was releived but then just after few minutes I made it a mass,
luckily lab assistant was cooperating so I was saved
@@busyinverse4300
The problem here is that it's my second year of high school and i'm taking this in physics class so it's pretty random.
cm must be converted to m ,the SI units
Does anyone know?... Please give me one (or a few) examples of oils that don't mix with water and have a very low density. Non toxic, non explosive, non volatile at ambient temprature.
For example... olive oil. But it's too dense (92% density of water). Anything much less dense?
If the density has metres why didn't you convert the cm into metres?
i cant find it with three different liquids :(
maaaaan thanks
watching u tubes on youtube
Rho looks an awful lot like p. You should have spelled out density for water in the sentence at the top so students don't confuse it for pressure. Good video btw!
So easy😌
Thnks
the units arent right. density is in kg/m^3 and distance in cm
Pressure SI unit is Pa which is Pascal
There is a mistake in example 1. When calculating the height: density of water x height of water :1000x80(cm).. 80cm is wrong.. u need to use meters; 80cm= 0,8m
U dont need to use meters
Thanks teacher amazing
u need to use meters
Since the cm is on both sides of the equation if doesnt matter
@@farrahwarraich6924 but shouldnt you convert cm to m because the density is defined in m? Even tho dat units of densities "cancel" each other, the densities were still defined for meters not centimeters?
Why didn't he convert to metres in #2...😐
teaching about u tube in you tube
That's actually funny 😂💔
Dear organic chemistry tutor, it is really hard for me to hear your voice. Please speak louder. Thank you
Love you man..
No homo
love you too bro
sizikuveka ase
you are slow and lack in explaning
I still have a question ; what happens when the U tube Manometer contains three or more liquids? How to calculate the height or density of one of the liquids.
In case of equilibrium of more than two liquids in U- shaped. Tube: Density¹×h¹=Density²×h²+Density³×h³
