Foot Water (4°c)
Foot water (4°C), symbol ftAq, is a unit of pressure representing the height of a water column at 4°C that exerts a specific pressure.
History/Origin
The foot water (4°C) has been used historically in engineering and scientific contexts to measure pressure, especially in water-related applications, as an alternative to other pressure units like inches of water or meters of water. Its usage dates back to traditional measurements in hydraulic and civil engineering.
Current Use
Today, foot water (4°C) is primarily used in specialized fields such as hydrology, water management, and engineering to measure low pressures, particularly in systems involving water flow and pressure head calculations.
Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
