Why does the river nile flows uphill

The water again flows upward because the pressure in your mouth is now greater than atmospheric pressure. The water pressure can also be adapted by changing the amount of water that is raised above the water that is coming through the water line. When you open a spigot, however, the water pressure at that spigot decreases somewhat, and because a larger pipe provides a lower resistance to flow, the water pressure will decrease less with the larger pipe.

For example, the heart of a resting adult pumps blood at a rate of 5. A toilet will normally use about gallons per minute gpm , a shower from 1. A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found on the main water-supply pipe; look for a conical-shaped valve next to the water meter, close to where the main water pipe enters the house.

Then, tighten the locknut to secure the valve. Question Last updated Oct 07 Originally posted Aug 14 AM. Your Email Address:. Index Newest Popular Best. New Player Log In. Can elephant ivory and rhinoceros horn be humanely harvested as a commodity, to save the species while pre-empting the poachers? Louis E. Barragan Sr. El Paso, Texas. Unfortunately, harvesting tusks and horns is not a viable option. Normally, we think in of terms of water flowing downhill or from one place to another because of gravity, which is partially correct.

Since all surface areas are measured by their distance from the center of the Earth — not just from the surface up — then water will flow from a point that is farther from the center of the Earth to a point that is closer.

This distance can vary by as much as a few miles to as little as a fraction of an inch. Think of mountain creeks cascading into a lower pond, which then drains into a stream that might become a tributary flowing into a lake that spills its contents into a river that eventually reaches the ocean. Each step of the way is lower in elevation than the previous one, but also closer to the center of the Earth. Either direction we care to go, if we travel a mile or 10, miles, we will still be influenced by the same universal gravitational field.

The same holds true for the Nile or Mississippi River.
