Description

Inch of Water (inH₂O): HVAC and Fluid Mechanics

The Inch of Water (inH₂O) is a unit of pressure defined as the pressure exerted by a column of water one inch high, approximately equal to 249.0889 Pascals. It is widely used in the HVAC industry to measure air pressure in ducts and ventilation systems, as well as in fluid mechanics for low-pressure measurements.

Understanding the Pascal (Pa)

The Pascal (Pa) is the SI unit of pressure, named after the French mathematician and physicist Blaise Pascal. It is defined as one newton per square meter, representing the pressure exerted by a force of one newton acting uniformly over an area of one square meter. The Pascal is widely used in various scientific and engineering applications to quantify internal pressure, stress, Young's modulus, and tensile strength.
