You can do this because it takes more pressure from the pipe to flow water to the upstairs tap than the amount of pressure it takes to flow water to the downstairs tap. This is clear in Bernoulli's Equation: The fancy-looking p (pronounced rho) in the first two terms represents the density of the liquid, v represents the velocity in which the fluid is traveling, g is the acceleration due to gravity (appx. 9.8m/s^2), and z is the difference in height traveled by the fluid, the final P represents the atmospheric pressure (101.3 kPa). As you can see, as the value of variable z decreases, it allows for the only other variable, v, to increase. This explains why, at a higher elevation and a constant force applied to the fluid, water will flow faster at a lower height than a higher point. EDIT: It won't let me add an image for some odd reason, search Bernoulli's Principle and look for the phrase, "By multiplying with the fluid density", and reference the equation underneath for a more complete understanding of what I just said.
The mains supply wave shape is known as a sine wave. It represents the alternating current that is provided by electrical utilities for powering our homes and businesses.
The bulb in the frequency of AC mains by electrically vibrating rod acts as a visual indicator of the frequency of the vibrations produced by the rod. As the rod vibrates at the frequency of the AC mains, the bulb will flicker or light up in synchronization with the vibrations, providing a way to visually observe the frequency.
The only difference between the way a fluid exerts pressure and the way a solid does is that a fluid flows into any available space, and so it exerts pressure very evenly. If you want a more detailed analysis, ultimately physical matter exerts pressure by means of the electrostatic repulsion between electrons.
A hydrophore system is a system comprising a powerful pump unit and a pipeline that is designed to increase the pressure of water from the urban mains so that water can be supplied to the higher storeys of a tall building.
The velocity does not depend on ther shower head, however it does depend on the cold mains pressure, a higher pressure will result in a higher velocity, and visa versa.
How to reduce your water pressure to your taps if you have a high mains pressure or an unvented cylinder such as a megaflow, boilermate ect. Reducing water pressure in your home can be done in several ways, my video demonstrates a few. Some people turn down the isolation valves or main stopcock which is not advisable, as it can produce noise, water hammer in pipes /taps and can damage the valves and stopcock.
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
The heart and lungs
In a typical municipal water system, water pressure is caused by gravity. It works like this: Water is stored in a reservoir which could be underground or above ground. From here it is pumped through a filtration and treatment system, then into tall water towers. From these towers it is gravity fed to the water mains under the street that supply water to the houses, shops and factories. The reason for pumping the water to a tower first, and not directly to the mains, is to avoid fluctuations in pressure during periods of high and low usage. In a rural or cottage system, there is often no buffer tank, so the pressure fluctuates up and down constantly as you use the taps.
In a direct system of cold water supply, the cold feed pipe serves to transport water directly from the mains supply to various outlets, such as taps and appliances, without the need for a storage tank. This pipe ensures a constant and immediate supply of fresh water at mains pressure, allowing for efficient usage in residential or commercial settings. Additionally, it helps maintain the water quality by minimizing stagnation, as the water is continuously supplied from the mains.
Force mains are pipelines used to transport wastewater counter-gravitationally (i.e. from lower to higher point). They must include some pumping device, and often are pressurized.
AMF stands for Automatic Mains Failure, which is a system that automatically starts a backup generator to supply power in cases of a mains power failure. The AMF unit constantly monitors the mains power supply and switches to the generator when it detects a failure. Once the mains power is restored, the AMF unit switches back to the mains and can shut down the generator.
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
Copper is commonly used for cables in ring mains operating at voltages of 230V or higher. Copper is a good conductor of electricity, allowing for efficient transmission of power, making it suitable for high-voltage applications.
