Inch of Water (4°C)
pressure • Non-SI
Definition
The inch of water (4°C) is a non-SI unit of pressure defined as the pressure exerted by a column of water 1 inch high at a temperature of 4 degrees Celsius, where water reaches its maximum density. This unit is commonly used in various engineering applications, particularly in HVAC systems, to measure pressures in fluid systems. It is approximated as 0.0361 psi, serving as a practical measurement for pressure in systems where water is the working fluid.
History & Origin
The inch of water has its roots in the traditional measurement systems originating from ancient civilizations, where pressure was often gauged based on the height of fluid columns. The specific reference to 4°C is due to the unique properties of water at this temperature, where it achieves maximum density. This measurement has been standardized in various contexts to facilitate fluid dynamics calculations and engineering applications.
Etymology: The term 'inch' comes from the Latin word 'uncia' meaning 'one-twelfth,' indicating its relation to the foot. 'Water' indicates the fluid medium being measured, while '4°C' specifies the temperature for precise density.
