P is the pressure, ρ is the density of liquid, and the density of water is 1× 10? kg/m？ G is the acceleration of gravity, 9.8n/kg, and h is the height from the pressure point to the liquid level. Water pressure has nothing to do with water quantity, but only with the depth and density of water. The deeper the water, the greater the water pressure; The greater the density, the greater the water pressure. In real life, the water pressure at home is also affected by the bending degree of water pipes. The more bending times, the lower the water pressure.

Basic parameter

Generally, the tap water pressure is about 0.7 kg, and 1MPa is equal to 10 kg. 1MPa= 10kg/ cm2, and MPa MPa is the new unit.

According to the tap water supply standard: tap water is generally considered as 0. 1MPa = 10m, and the water supply pressure at the end of the pipe network stipulated by the state is 0. 14Mpa. More intuitively, 0. 1mpa is equivalent to a standard atmospheric pressure, and the water supply pressure at the end of the pipe network is 0. 14Mpa, which is equivalent to the faucet leaving the water supply tower. Therefore, the higher you live, the lower the water pressure will be.

1. Water pressure has nothing to do with water quantity, but only with the depth and density of water. The deeper the water, the greater the water pressure; The greater the density, the greater the water pressure), in real life, the water pressure at home is also affected by the bending degree of the water pipe, and the more bending times, the lower the water pressure will be.

The deeper the water, the greater the water pressure.

At the same depth, the water pressure exerts pressure all around.
