What are the diameters of the pipes and volumes flow rate of the water tap?

3 and 4

nose user, es una tarea para el kinder?

100 cm. 1mL/sec.

8 minutes per hour

3

3 then if we're leaving some room at the top so it doesn't spill over

1, assuming the amount of water being added is the size of a tsunami

3 and 4 at the same time

lol

none, mexican didn't pay the aqua bill

Lets play a game of: Kidding or Retarded!!!

Have you not seen a watering can before?

The diameters of the pipes aren't going to help tou unless you're willing to bust out a simplified version of the navier stokes equation and look up crazy stuff like energy losses from sudden openings and surface roughness. The higher the water level in a given tank is, the more delta p and the higher flow rate there will be. It's going to get complicated enough to be a tossup between several of the tanks unless you accept the flow out of the tap to be small compared to any flow from one tank to another.

If we do consider the tap output to be small (such as a steady drip such that equilibrium is essentially present at all times), then tank three will fill to the level of the entrance at four until the level in four reaches that same level, at which point both will fill simultaneously. Because tanks three and four have open tops, tanks two and one will never fill beyond the shallow area beneath their exit pipes.

Sorry, correction. Tank two will fill to the height of the openings at three and four

The obvious answer is 3vand 4 at the same time. But realistically that's not possible. If both required only a single molecule to be full then for some fraction of a second 3 must be filled before 4. It would take time for the presence of that last molecule added to tank 3 to propagate any effect to tank 4. Probably about the speed of sound in water. It's probably random then whether 4 and 3 would be full i think it would flip between the two until another molecule of water was added.

Do you know what "full" means?

Except your wrong, my dude. It will totally matter. If the water tap is going to fill up at a gallon a second and youre using a capri sun straw to connect the tanks then tank 1 will fill up first because volume rate in is larger than volume rate out.

Yes

Have you not seen a doctor to diagnose your mental retardation?

1 then 2 then 3 and lastly 4

3 & 4, because of the equal waterpressure

It's 3 you fucking card carrying retards

Not enough info to say. If the volume of water added is more than the flow to 2 then 1 fills first. Would have to know exactly how much water is being added and how much water can pass.... that’s also assuming all 4 containers are equal as well. This is dumb.

That's one scenario. Another is that the water level in 1 can become high enough that the pressure differential increases output flow until the flow out of 1 equals the spigot, at which point it won't fill further until tank 2 is filled. If tank 2 has the same dimensions (including pipe) as 1, it will be the same situation. Depending on the force needed for the flow out to match the spigot and the depth of the tank, the level in 2 could back up to the output of 1 before dynamic equilibrium csn be reached, and as a result the reduced delta p on 1 will cause its equilibrium level to rise even further. And that isn't even considering 3 and 4.

3 and 4.
I'm a certified plumber, trust me.

Your asshole with my nut op, you fucking faggot.

that's certainly a unique way of coming out

That's only if flow is close to equilibrium at all times and it isn't a dynamic system i.e. the pipes connecting the reservoirs permit flow much larger than what the spigot puts out.

3

Did you even read my post?

4 then 3

That's not implied at all in the picture, stop trying to be a fucking faggot smartass.

What the fuck did you just fucking say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills.

I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words.

You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands.

Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your fucking tongue.

But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it.

You’re fucking dead, kiddo.

ever heard of physics

Did you just think that you could fucking fool me with that comment of yours? I've searched your name up in the Navy SEAL database and you have never even graduated BUD/S, hell, even served in the Armed Forces. If you were actually a Navy SEAL, then you actually know how to spell guerrilla, you fucking moron. And you say you are the top sniper in the entire US Armed Forces and have over 300 confirmed kills. If that were true, then why the fuck is Chris Kyle a household name and you aren't? And plus he only had 160 kills. You think you can get away with saying that shit to me over the Internet? Think again, fucker. Plus why the fuck would you say you have a secret network of spies yet you just revealed that you had your secret network of spies? Are you a fucking idiot? If you can kill someone seven-hundred different ways, then list them all, I bet you can't even come up with seven. And if you had access to the entire US Marine Corps arsenal, then why the fuck did you just say you were in the Navy SEALs earlier? If only you could have done your research prior to posting your little “clever” comment, maybe you would have held your fucking tongue. But you couldn’t, you goddamn idiot.

He's actually right.
Ever heard of math?

Touche, nigger.

Nothing is implied in the picture. It's like being shown clipart of a cartoon boat and a cartoon elephant and being asked if the boat will sink with the elephant. You're given no details and you need to come up with different scenarios.

In the problem, two regimes exist. One where spigot flow is small (in which case the problem is simple and 3/4 fill up at the same time) and one where spigot flow is large (in which case tons of factors they don't give you can affect the outcome and you then have to break it down into a gazillion other scenarios).

Case one is fluid statics and is easy. Case two is fluid dynamics and has many answers depending on more details than they give you. A description of both cases is needed for the full answer.

Thats a lot of water for that to happen with just the weight of the water alone. The question is really open ended.

I skimmed, its really late. I kinda forgot halfway through what I was reading. Forgib me fellow engie brah

It depends less on the amount of water than it does on whether the proportions of each part allow the condition to exist. A good example is if the pressure at the bottom reaches the spigot pressure and it's similar in diameter to the choke area in the screw valve. If the valve's cracked and the tubes aren't coffee stirrers, the situation could totally arise

It be neat to throw it in fluent if I had the time

Also good to point out that the bottom of bucket 1 doesn't even have to come close to spigot pressure, if the pipe is far larger than the spigot's valve choke. At that point flow in can equal flow out.

Now that's taking a Sup Forums shitpost as far as it needs to go, lol

especialy this
You win the retard award, congratz.

As it has been correctly stated by a few anons allready, it depends wether or not the waterflow from the sink is sufficiently higher then the waterflow through the pipe (an integral has to be solved as the pressure may change).
Considering this, its either 1 or 3 which is filled first.
I think it should be possible to fill in following orders
3412, 3124, 3421,1342 I am pretty sure there are no other combinations, correct me if I am wrong.

the mortal one

>if pressure reaches spignot pressure
I know what you wanted to say, but it the waterflow that has to reach spignot waterflow, and its a little more complex then this, it may never reach it while 3 and 4 are allready full.

It is either 1 (flow from tap greater than flow through pipes) or 3 and 4 simultaneously (flow is less than flow through pipes. Three may almost fill, but the second the level is at the level of the pipe leading into 4 3 will stop filling until both are identical and then both will fill.

UNLESS
all of the pipes have completely different diameters, in which case we have insufficient information.

Assuming equilibrium, 3 and 4, like I said.

>If i color the water in maybe it will make more sense
Why don't you read a book instead you dim-witted faggot

It's algodoo.

>fill
None

Kek

Oh, it's a neat physics engine. Nevermind. Pretty cool

1 so the other would be fully filled
>learn physics fags

If the waterflow is greater then 0 and it has to be, 3 will fill faster then 4 in any case.
As pressure needs a finite time to be in equilibrium.

3 first, then 4

i would mention water surface tension but then the flat earth fucks will go REEEEEEE.
