Mercury Barometer Problems, Physics - Air Pressure, Height & Density Calculations - Fluid Statics

This physics video tutorial provides a basic introduction into the mercury barometer. It explains how a basic barometer works. It explains how to calculate the atmospheric pressure of a two fluid barometer in addition to calculate the height of a mercury column given the air pressure. In addition, this video contains a practice problem that illustrates how to calculate the density of an unknown fluid using a barometer.

You deserve a Nobel prize. You have touched more lives than you know. Keep up the great work.

[@alexafinishmydegree112]

Been watching you since i was in 1st year when my friends suggested your account to me. I’m now almost ending my last year with a class that covers our 4 years cover to cover, and i still watch your videos for review. Thank you so much i dont know how i would’ve passed my classes without your videos

[@enochbrown8178]

You, sir, are the best! I've viewed just about every video covering this concept. Yours is by far the best!!!

[@Rodddy]

I've never hated anything more than the barometer question

[@ritesha8050]

Yep and resultant forces

[@cheap_skates]

yes same

Alright guys I am going to say it
It looks like a d---
My lawyer has advised me to not finish the joke.

[@dabare7]

I’m only 3 minutes in and I FINALLY understand the correlation of InHg to altitude when adjusting the altimeter to correct for pressure!

Thank you, You are Great teacher! :D

[@junelynzaspa6135]

hello, good afternoon. can you include the unit in every equation. like how the N and kg being cancelled ang also how the m/s being cancelled. its quite good and I am one of your subcribers. It seems complicated in deriving unit.

At 10:10 we are assuming they are at the same atmospheric height, otherwise we could not nevessarily equate that

Please how do I go about this question? an empty bottle is corked when the air inside it is 10⁰ and the barometer reads 75cm of mercury. if the cork blows out when the pressure inside the bottle exceeds the atmosphere's pressure by 10cm of mercury. calculate the temperature to which the bottle must be heated to cause the cork to be expelled

Thank you 1.a metal wire 7.5m long and 1.5mm in diameter stretches 4mm. when a load of 10kg is hung on its end find. a. stress? b. strain? c.youngs modulus?

[@Iconic_dahlia]

Stress=Force/area
Force=mg=10×10=100N
1.5mm in diameter
Radius=diameter/2
Radius=1.5/2=0.75mm=750m
Area=πr²
Area=3.142×750×750
Area=1767375m²
Stress=force/area
Stress=100/1767375
Stress=5.658×10^-5 N/m²
Strain=extension/length
Extension=4mm=4000m
Length=7.5m
Strain=4000/7.5
Strain=533.33
Young modulus=stress/strain
5.658×10^-5/533.33
Young modulus=1.061×10^-7N/m²

[@alexlow9714]

4:47 Is it a must to convert the m into mm?

[@alexlow9714]

can i leave my answer as 76cm? Or i have to put 760mm Hg?

[@latenightsinthecity_]

@@alexlow9714 yes, in most of the cases, because mm of Hg is the standard unit

[@peanutbutter315]

Question. Why do we change the pa to kpa to get the Atm can we just got from pa to Atm?

[@taimarishi7048]

Thank you so much omg

[@furejul7619]

6:38 why the athmosphere pressure is different with the pgh while in 3:55 it is the same?

[@ridaz3151]

In the first question, you are calculating the height of mercury which is 76 cm
In the second question, the height given of mercury is 72 cm. That's why the atmospheric pressure values are different

[@mouseinahouse4670]

Thank you

[@SnehaJakhotiya-fz1ft]

4:26, on dividing we get 1.3 and not 0.76.

[@anilkumarsharma1205]

put a neodymium magnet in test tube so when pressure increases and decreasing then magnet also going up down, now we use a coil around the test tube and we got that induced electrical forces by lazes law, now we have a energy source if we increases this setup one lakh times with water column

[@mehmoonanoorm8196]

Good

[@marsthewargod2095]

what if temperature is one of the variables?

[@codycasanova2579]

The density of the unkown fluid you solved for was not in the correct unit since you used cm

[@poorleatherwallet]

A mercury barometer registers a reading of 760 mm. If a piezometer using water were to be used to measure the atmospheric pressure, it would require a height of ____?

[@anilsharma-ev2my]

Show exactly near the sea
How mercury going to increase the. Volume or not ?

[@anilkumarsharma1205]

we got a very high voltage just by simple neodymium magnet big blocks and we used it for charging battery, so we got energy which is almost free maintenance free for millions of trillions of uncountable years
