Excellent! Can you please show how to calculate horizontal pressures at various depths when using oil and water?

[joysao]

Nice and easy to understand explanation, thanks 👍

[darylstricker]

nice video - the result given would be in absolute pressure of course (not gauge pressure) just for peoples reference

[danielasepulveda]

How would you find the force on the sides of the container. Would you need to integrate and add the oil then the water. Or there a specific way to do so?

how to calculate gauge pressure if same built question

[CptMaahir]

in the equation p1 = p0+ pgh how come you need to add the p0 into it?

[azizizizi]

Why oil has higher density than water? Pls reply me. We know that an object with high density sink. (sorry bad englishg

[jruby]

If pressure at atm was zero this would totally change your answer right? Don't you usually assume Pressure of atm to be zero?

Thanks. Great video!!

If the tank is full and covered with a lid, will Patm be zero?

[IsmailAli-zcfm]

if the shape of the tank was not constant how would that affect the pressure ? like lets say it was a square then a cylinder?

[godwingeorgemartin]

What is the pressure at the interference of these two fluids

[andrewchoi]

Damn, it's really the little things that suddenly cause things to click. You saying that SG of 0.8 means it will be 80% as dense as water suddenly made specific gravity fall into place for me.

[bennett]

how would you find the force on the bottom of the tank in N?

[edgarasm]

Does a water density in the middle of water (height 1.25 m) is less then density at the bottom? I mean water density is not const., but the difference is so small so we ingore it? Because density also depends on pressure, not only by temperature.

[junghoainam]

so the pressure at the bottom is P2 or P1+P2 could u tell me ?

[fatinnabihah]

What is the actual value of atmosphere pressure? 101kPa or 101325Pa? I'm confuse

[Dogface]

Would this be set up differently if the tank was a cylinder with a specific diameter?

[bijuisaac]

Is there any pressure difference between closed and open water tank which is full of water?

[thierryosborne]

Why applying Patm ? I mean it surrounds the whole tank so its effet cancels itself no ?

[purpohpenguin]

What if the container is closed at the top?
