Inch of water

La inch of water (inH₂O) at 4 °C est une unité de pressure égal à the pressure exerted by a one-inch column of water at its maximum density temperature, approximativement 249.089 pascals. Il est widely utilisé en HVAC engineering, duct pressure measurement, and low-pressure gas regulation. Because water is much less dense than mercury, the inch of water represents a much smaller pressure than the inch of mercury


pascal

La pascal (Pa) is the unité SI dérivée de pression, défini comme one newton per carré metre (N/m²). Il était adopted by the General Conference on Weights and Measures in 1971 and nommé d'après the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximativement 101,325 Pa, and il est widely utilisé en science, engineering, and meteorology.
