Water pressure
Water pressure in the physical sense describes the hydrostatic pressure within the water. As the water depth increases, so does the surrounding pressure . One speaks of the water column . It is especially important for divers to know what pressure their body is exposed to in order to assess the gas saturation of the body tissue and to avoid diving illness .
One meter of water column (mWS) = 9.807 k Pa ≈ 0.10 bar
Water pressure in the technical sense describes the line pressure of the water with which it is pressed into the pipe or under which the water in the water pipe is.
- In the past, this supply pressure was realized by water towers in which the water was exposed to the pressure of gravity . The higher the water tank, if available in the vicinity of the requirement, also installed on hills or mountains, the greater the pressure in the pipe.
- Today the pressure is generated by pumps . A distinction is made between pipes with normal pressure (domestic water pipes) and pressurized water pipes that are under considerably higher pressure.
