Class 11 Physics | Fluid Statics | #4 Fluid Pressure due to Gravity | For JEE & NEET

[@luciferevan9230]

respected sir at 7:39, we found the pressure by considering net force / surface area (horizontal rectangular slab like region on level of pt x), so while finding gauge pressure, if the vessel was fully erect up to height h (with same width of container as how much it is in its bottom) the fluid, and in the case sir has shown with funnel's example. in both the cases denominator (ie surface area remain same) but both will exert diff forces as mass occupied (or volume) by fluid is different in both cases so how to account this sir? plse correct me!!!

[@physicsgalaxyworld]

pressure due to fluid only depends upon the column height not on the base area... this comes from Pascal's law that in a horizontal level (or level normal to effective acceleration of the fluid body) the pressure at all points remain same... so shape of vessel will not affect as the excess or less weight of fluid is balanced by the force by side walls of the container... watch all videos and advance illustrations in sequence to understand the logic by examples... on PG youtube channel or www.physicsgalaxy.com

[@AyushKumar-nl9yd]

Sir these videos are enough to get seat in IIT .

[@physicsgalaxyworld]

yes... but you also need to watch our adv illustrations to boost your confidence on concepts for jee adv applications...

[@technologyeducationzone7763]

Sir, if thin is vessel then at pt A then less is the mass of liquid then a wide vessel .So, pressure need not to be same as it experience pressure due to whole wt of liquid

[@ujjwalchitransh6411]

Sir if at x net "inward" force/pressure exist then why in diagram arrows are pointed 'outward' in fbd of 'x'.?

[@adarshchaturvedi3498]

considering a particle to be a spherical molecule , then in the pressure calculation net pressure (h.rho.g) will be due to all those molecules having centre above the centre of the concerned particle na ?

[@physicsgalaxyworld]

Net pressure at any point is due to the weight of all the particles and any external pressure present anywhere on the fluid body and it acts in all directions at that point...

[@anonymousone3024]

Sir if at any point pressure is due to height column above tht point But we also consider tht point is at equilibrium because it gets equal pressure from all directions

titanic submarine people shouldve seen this before going in 😞

Ya😢

[@Sazid-j5q]

why / as far as i remmber from the movie they died of temperature and not the pressure.

Sir at 1:30 how m=hsp

[@princekumar-rl1dm]

Sir at point x pressure from all sides are equal so object would float or sink..

[@tokyonaorem]

Sir explanation in all videos is very shortcut n complex, thinking that we students r all expert. Sir please mention some basics also while teaching..

[@physicsgalaxyworld]

videos are starting from basics only... you need to watch all our videos in proper sequence... you can also watch our videos in proper sequence on all topics on our website www.physicsgalaxy.com

[@gmmkeshav]

sir how to proof that fluid pressure does not depended on shape of container

[@physicsgalaxyworld]

By Pascal's law !

[@CortexMatrix]

Is it necessary to refer to book examples or straight away jump to questions

[@physicsgalaxyworld]

reading examples is always helpful... first read out examples que and solutions then attempt all to analyze yourself... then start unsolved questions...

[@prabhatkumarverma200]

very nicely explained sir

[@anuhyamishra252]

@Physics Galaxy Respected sir , fluid pressure is the gauge pressure value or the gauge pressure + P atm value?

[@tpsicmin]

Thanks A Lot Sir ❤❤❤❤

[@sathvikbhagavan9920]

Sir but the volume of water above all the columns is not same then how pressure came out to be the same at all the points at same level

[@physicsgalaxyworld]

+Sathvik Bhagavan According to Pascal's law at a horizontal level or in a level normal to effective gravity on the contents of container... always pressure remains same...

[@rgopi2549]

@@physicsgalaxyworld sir but pascal law is right in case of enclosed vessel,right sir?

[@SumaidSyed]

Sir,you are saying the liquid particle X will experience pressure from all directions,but while calculating magnitude of pressure we used only weight of water column above the particle?So,isn't that particle experiencing pgh pressure only from upward?

[@physicsgalaxyworld]

+Syed Sumaid It is due to the weight of liquid only but it acts in all directions due to spherical molecules and contact reaction between all molecules...

[@vanshmishra7119]

the lower part beneath x also exerts force then why it doesnt gets counted for pressure

[@razeetnitwg]

Here they are calculating the pressure acting on solid.As you said,the solid exerts a reaction force back on fluid.Suppose we a take a point in fluid also,we are calculating the pressure acting on it from top,a reaction force will act on it from bottom,so the fluid is static.

[@anutejkardele2212]

what happen to row of water

[@physicsgalaxyworld]

pl specify what exactly you wish to ask and mention the time instant of video concerning to your query...

[@SaurabhKumar-us3ty]

Sir if fluid applies inward pressure on solid cube from all sides why doesn't it get squeezed?

[@physicsgalaxyworld]

because it is rigid...

[@nikhilnainwani]

Thankyou very much sir!

[@khushbusharma1853]

Sìr how can we say that pressure exerts equal forces in all directions??????

[@naturelover4148]

The particles need to be in equilibrium so they must exert equal pressure in all directions for the forces to get balanced

Not everyone in India speaks the same tongue, so english is an overall better mode of conveying information than any "own language" you are talking about kind sir.
