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.
Kilonewton/square Meter
A kilonewton per square meter (kN/m^2) is a unit of pressure equivalent to one kilonewton of force applied over an area of one square meter.
History/Origin
The kilonewton per square meter is derived from the SI units of force (newton) and area (square meter). It has been used in engineering and scientific contexts to measure pressure, especially in fields like civil and mechanical engineering, since the adoption of the SI system.
Current Use
Today, kN/m^2 is commonly used in engineering to specify stress, pressure, and load measurements, often interchangeably with the Pascal (Pa), where 1 kN/m^2 equals 1,000 Pa.
