Everyone: What is 1 mm of water column equal to in Pa?
10 meters of water column corresponds to one atmosphere of pressure, which is 100,000 Pa; you can do the calculation by yourself, haha
10Pa, man. :lol
Strictly speaking, it should be 9.8 MPa.
Guy: P=M/S=density*height*9.8. The pressure corresponding to 1 millimeter of water column is 9.8*1000*0.001=9.8
Generally, 1 atmosphere is equal to 10 M, which is around 10 Pa. A more precise calculation can be done using the formula for pressure, but what is the use of such a low level of pressure?
1 Pa = 1 N/m2 ≈ 0.1 mm.WG; 1 mm.WG ≈ 10 Pa. WG refers to the pressure exerted by a water column, similar to the pressure exerted by a mercury column
1 millimeter of water column (mmH2O) = 9.80665 Pascals (Pa) 1 millimeter of mercury (mmHg) = 133.322 Pascals (Pa) 1 engineering atmosphere = 98.0665 kPascals (kPa)
1 mmHg = 133 Pa. The density of Hg is 13.6 times that of water; therefore, 1 mmH2O = 133/13.6 = 9.78 Pa
Standard atmospheric pressure is 101325 Pa, which is equivalent to 760 mm of mercury. Therefore, 1 mm of mercury corresponds to 133.3 Pa. Since the density of mercury is 13.6 times that of water, 1 mm of water column is equivalent to 9.8 Pa of atmospheric pressure.
No way, it’s that high – it’s almost at high voltage already:lol
1 atmosphere = 760 millimeters of mercury = 10 meters of water column = 1.013×105 Pa; just do the conversion yourself and don’t let others mislead you. :lol
