Woooow! Stop on Bros!

3moses:
most nairalanders are olodos....
3 & 4 filled to d brim at d same time...
this is called law of equal proportion...

tk4rd:
Water will always find its level...
No internal pressure is needed here, because the tanks are not air-tight closed...
Remember that the top is open to the atmosphere, so, only atmospheric pressure and gravity play all the roles here..
Let me ask you something......
SHEEY YOU ARE VERY GOOD IN "OPEN RESERVOIR HYDRAULICS".??

femi4:
Water always find the easiest root.
This is simple engineering design.......you piped downward not upward when you are far from the pump

Please make sure you watch this video.. Then, if you have any other thing to teach me, you first refute the facts in the video, and come up with your valid points.

ladyF:
My answer is tank 3.

Tank 1 can't get filled up because it keeps losing water to tank 2.

Tank 2 can't get filled up because it keeps losing water to tank 3.

Tank 3 can only start filling up tank 4 once it gets sufficient volume/pressure to push water up that height to tank 4. So it's going to get filled up before tank 4 does.

Hope ayam not an olodo o. Oya clap for LadyF.

It's LadyF again

femi4:
I don't do copy and paste. That video is incorrect.

Tank 3 will overflow before 4.

By applying Bernoulli's equation, we
can actually calculate the water level (head) difference of the two tanks to be:

h = (Q / A)^2 / (2 * g)

Where Q is the flow rate between the tanks and
A is the cross sectional area of the connector.

Say we have a A = 1.6 square inches (about the size of a quarter), and that Q = 20 gallons per minute.The water level in tank 3 will be 3 inches higher than in tank 4. Also, if you account for friction losses, this height difference will actually be even greater.

tk4rd:
The size or cross-sectional area of the connector have nothing to do in this case.. This is not a case of "closed pipe hydraulics" neither is it a case of "pipes under pressure"..
All that matters here is "Atmospheric Pressure", "Gravity", and "difference in level between the connectors"..
Since all the tanks are open to the atmosphere, the atmospheric pressure will always ensure to balance the water levels in the tanks once they are above the highest point of the highest interconnecting junction in the whole set up.
Therefore, at the point when Tanks 3 & 4 are full and overflowing, the water in Tank-2 will maintain a level that is equal to the top level of the water in Tanks 3 & 4; and if you observe carefully, this final water level is above the points of interconnections between the tanks.
Even if the water from the tap above stops flowing, the water in Tank-2 will remain stable at the level coinciding with the top of Tanks 3 & 4. Also, the water in Tanks 3 & 4 will remain full and stable without overflowing until the tap above starts flowing again.

thankyou for the video jare . My Nigerian brothers and sisters will be arguing a matter of simple common sense without engaging their brains and will not agree until they see oyinbo man tell them otherwise.

Olodo... Tank 3 will get filled up first

martineinstein:
open your eyes...number 1 will get filled up and others won't

vodutive:


I cry for my people!! these are the kind of questions employers ask graduates to test their ability to think. Can a container with a hole fill up? How can 3 fill so long as there is an opening? yet they are all there shouting 3!!!! Some are there writing formula!!! It's not a physics question, it's common sense test.

Happy new year. Beeeeereee!

Spandy:
If the pressure from the water source(tap)is very high, I think tank 1 will be filled up first before any other tank owing to the tiny size of the pipe linking eachother.

Well, I didn't get 'em
