Answer 1

Вода поднимается по тубам с помощью насоса

Answer 2

Why does water rise up in pipes in a water supply system?

Water rises up in pipes in a water supply system due to a combination of factors, including pressure differentials, gravity, and the principle of fluid dynamics. When water is supplied to a building or a house, it is typically under pressure. This pressure is created by pumps or by the elevation of the water source, such as a water tower. The pressure forces the water to flow through the pipes and reach the desired outlets, such as faucets and showers.

Pressure differentials play a crucial role in pushing the water upwards. According to Pascal's principle, pressure is transmitted equally in all directions in a fluid. When water is under pressure, it exerts force on the surrounding areas, including the walls of the pipes. This pressure is transmitted throughout the system, allowing the water to rise up in the pipes and reach higher levels.

Gravity also contributes to the upward movement of water in pipes. Gravity acts as a pulling force, causing the water to flow downwards. However, when the pressure in the pipes is higher than the pressure outside, the water is forced to move against gravity and rise upwards.

The principle of fluid dynamics explains how water flows through pipes. According to this principle, when water flows through a pipe, it experiences a decrease in pressure as it moves faster through narrower sections of the pipe, such as bends or constrictions. This decrease in pressure creates a suction effect, which helps to draw the water upwards.

In summary, the combination of pressure differentials, gravity, and the principle of fluid dynamics allows water to rise up in pipes in a water supply system.
