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 said

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.

fluid mechanics expert.... tank 1 will get filled first

fluid mechanics expert....

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.

hmmmm...how about if tank 1 gets filled up first?

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

hmmmm..smh for u....the tanks get filled in order of 1234s

FIZIK:
Cannot say based on the information given.

How fast is the tap running?
How fast are the tanks losing water?
what level is full and how long does it have to hold water at that level?

If the tap runs faster that the outlets it would be 1 hitting the brim first followed by 2.
If not and assuming all outlets have equal capacity then 3 and 4 would progress simultaneously.

are ua mechanical engineer?

DEXTROVERT:
Tank 1 Will Be The First To Be Full To The BRIM

are u joking? u are actually correct

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

madam, if u studied fluid mechanics,u will realise that tank one will get filled upfirst

aaronson:
3

The more liquid in 3, the more force and momentum it gathers to forcefully push water into 4, Now how would that force come about? Container 3 will be filled up to gather in mass to bring about that force.

my dear, open your eyes...tank one will get filled up first..did u consider that the pipes are 3/ 4 of each heights of cylinders

chiraqDemon:
Tank 3 n 4 will overflow at the same time ..tank 1 and 2 will never fill up

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

1,

I can "your name" on the last line

i beg to differ,bro

where are beyonce,jayz,lady gaga,roberto de niro,kattie perry etc?

It's easier said than done. Some Americans are dumb if they think those companies will relocate to the states. The Google pixel and Iphone 7 cost a fortune despite been manufactured in China. What do you think the prices will be if manufactured at home?

the prices will skyrocket......i know trump cant do all what he said

ollah1:


It won't really affect China bro..

trump earlier said all american companies will cease outsourcing their hardwares outside USA...dat means apple and other companies with factories in china will be affected

ollah1:


Yh yh. You know what's up bro.. vladmir is all smiles right now.

even europe will be smiling...its only uk and china this election wud affect
