3:45 The Editing. Class.

Note *0.05* at 3:35 😅

[@mohammedanaskhan5772]

velocity at A is less therefore pressure there must be higher and hence P(b)-P(a) must be negetive........or is it that due to fluid pressure that pressure at B becomes higher ?

[@physicsgalaxyworld]

No... it is due to the height level... grav potential energy of flowing fluid is also to be accounted...

[@mohammedanaskhan5772]

is gauge pressure also contributing in it ?

[@physicsgalaxyworld]

its included in pressure at a point...

[@mohammedanaskhan5772]

At same levels I can understand the eqn of continuity can be applied!! At different heights how can we apply the equation of continuity, knowing that gravity is also having an affect on its speed.?

[@physicsgalaxyworld]

There is no such condition on equation of continuity for different levels... the liquid used is not compressible... you need to clear your basics here...

[@anmolempire1197]

But sir VB>VA thus PA>PB , hence pressure difference must PA-PB= -485 N/m², what wrong why pressure difference outh to negative

[@Gorh-van1]

Pressure velocity trade off is only valid when hieght is same

[@arjitarora9399]

Sir here it means Vb is same in all conditions either other part is above or below first part why increase gravitational potential energy you are not accounting : :

[@vasunith9682]

At 3:35 0.05 is strange

[@Harsh-iq1ph]

Vasunith S.parashar why, height difference is 0.05 when we take them in meter

[@nrjtech.1045]

It is edited out afterwards it seems, many times I have observed.

[@sapnasah1848]

sir,if i am calculating the answer in terms cm then it is coming negative........how is it possible sir?am i wrong somewhere?

[@physicsgalaxyworld]

what is cm

[@sapnasah1848]

centimetre

[@physicsgalaxyworld]

have you changed all parameters in cgs units...

[@aakashSky-0]

this is funny. the negative is probably because you are calculating (low pressure ) - (high pressure), instead of (high pressure) - (low pressure ). :)

[@akankshabharti1259]

use the value of g in cm...

[@vinaymayavanshi6534]

why no playback speed???
