Sorry to rehash this thread, but I was thinking about this question again and this comment caught my eye.
Is this how garden hoses work? Is there a pump somewhere that forces the flow rate to remain constant? enochnotsocool says that it is 'approximately' constant: does this mean that the...
That's what I initially thought would happen, tennispro1213. I think the difference (or the supposed difference) between this example and a garden hose is that in the case of the garden hose, the amount of water being pumped in is constant. That means that in order to counteract the smaller...
In a garden hose, is there a pump that is forcing the water into the hose at a constant rate? I was under the impression that it worked in a similar fashion to this problem but on a much larger scale - that is, instead of a small tank, there's a water tower.
In the example of a garden hose, is...
Won't the velocity of the water increase though as you cover half the nozzle? With a garden hose, covering half the nozzle makes the water spray out to a farther distance (i.e. with a greater velocity).
I'm not sure. I think that the flow rate might decrease because there's less of an area for the water to flow out, but I'm not sure if the velocity of the water increases as you decrease the area. If it does, then I could also see it being that the increase in velocity of the water in essence...
Let's say that you have an open tank of water and a hose connected to the bottom of it. Water is flowing out of the hose. You then cover half of the hose with your thumb. Will the flow rate (liters/second) right before you cover the hole be the same, less, or greater than right after you cover...
