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.

[@Rodddy]

I've never hated anything more than the barometer question

[@ritesha8050]

Yep and resultant forces

[@cheap_skates]

yes same

nah this is fine, the worst are logic gates...i can barely remember those stupid truth tables

[@enochbrown8178]

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

[@NickyNick9DoOr]

Dude, you're the GOAT

[@areebaiftikhar1322]

You are the BEST TEACHER!!! I understand Physics because of your videos. Thank You Soooo Much!!! :-)

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

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.

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

Thanks so much sir understood 🙏 the concept very well

Very phalic examples...

[@tomatrix7525]

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

thank you sir , helped a lot

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?

[@omowolemofeyisopeiyanuoluwa]

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

[@agbangukuran7945]

Weldon 🙌 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

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

[@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

[@SnehaJakhotiya-fz1ft]

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

[@mouseinahouse4670]

Thank you

[@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

[@vandheBharath]

Thanks man 👍👌

too bold of them to assume there are gonna be GCSEs this year

[@heinzguderian9572]

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 ____?

[@mehmoonanoorm8196]

Good

[@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
