Why does the stream of water travel farther when less water is flowing from the end of the hose?
When using a high pressure pump, you'll find that a smaller output nozzle gives *shorter* spray than a large nozzle. Small nozzles limit the flow. Yet with a garden hose things are reversed. Why?
It's because the long narrow hose and the pipes connecting it are acting like "friction." If you turn on the water, the hose rubs against the wate, and water flows relatively slowly out the end of the hose. Also, the water pressure at the open end of the hose is very low.
Now install a garden sprayer at the hose end. This will greatly slow down the water flow, and the effect of friction is greatly reduced. The pressure at the far end of the hose rises, and this high pressure can create a very long (but narrow) spray.
Another way to explain is with numbers. The greater the fluid resistance is to a constant flow, the greater the pressure-difference must be across that resistance. The fluid resistance value of the hose is large, while the resistance value of the hose-end is small, and since the same flow goes through both the hose and through its end-opening, most of the pressure-difference appears along the hose, while very little pressure-difference appears between the
hose and its opening. Now install a very narrow opening. If the fluid resistance of this nozzle is the same as the fluid resistance of the hose, then half of the faucet pressure appears along the hose, while the other half appears between the hose-end and the outside world. The nozzle has increased the pressure at the hose end. And if the fluid resistance value of the nozzle is much greater than that of the hose, then nearly all of the faucet pressure will appear at the nozzle.
So, to produce a long jet of water, use a very wide hose and a very narrow nozzle. Or even better, entirely get rid of the resistance created by the hose, and connect the nozzle directly to a high pressure water pump.
What else can I help you with?
The recharge of a stream is the volume of water flowing past a given point in the stream at a given time is this true or false?
False. The recharge of a stream refers to the process by which water from precipitation or other sources infiltrates into the ground to replenish underground water supplies, such as aquifers. It is not defined by the volume of water flowing past a given point in the stream at a certain time.
Is stream living thing?
No, a stream is not a living thing. It is a body of flowing water that moves continuously over the Earth's surface.
Increasing the steepness of a river's bed is LEAST likely to change the size of the discharge of a stream and the?
Increasing the steepness of the river's bed will have no direct effect on the size of the discharge of a stream. Discharge is primarily influenced by the volume of water flowing in the river. Steepness may impact the speed of the water flow and erosion processes, but it won't directly affect discharge size.
Is there a word for the small stream of water flowing southward down a mountain?
I know of no special name for southerly flowing streams. 'Draining in a southerly direction' would perhaps be a description.
What is a ephemeral stream?
A channel of an ephemeral stream always lies above the water table and only has water flowing through it as the direct response to recent and local precipitation.
What rhymes with deem (flowing water)?
Stream.
A small flowing of body of fresh water?
It is a fresh water stream.
Why does the stream of water travel farther when the nozzle of a hose is partially closed?
because you force it into a smaller space therefore you increase the pressure
Where in a stream would you find the maximum velocity of water flowing?
The maximum velocity of water flowing in a stream is typically found in the center of the stream, where the water is deepest and has the least amount of friction with the streambed and banks.
