Inches of water is a non-SI unit for pressure.It is also given as inches of water gauge (iwg or in.w.g.), inches water column (inch wc, in. WC, " wc, etc. or just wc or WC), inAq, Aq, or inH 2 O.
a = 553.6 L 2 kPa/mol 2 b = 0.03049 L/mol Liquid physical properties ... Note that the boiling point of 100.0 °C is at a pressure of 0.101325 MPa (1 atm), ...
Atmospheric pressure will decrease around 0.5 psi for every 1000 feet above sea level. As a vehicle descends from a high altitude location, the absolute pressure inside the tire remains the same, but the atmospheric pressure increases; therefore the gauge pressure will decrease.
Pressure (Torr, atm) Mean free path Molecules per cm 3; Standard atmosphere, for comparison 101.325 kPa: 760 torrs (1.00 atm) 66 nm: 2.5 × 10 19 [54] Intense hurricane: approx. 87 to 95 kPa: 650 to 710: Vacuum cleaner: approximately 80 kPa: 600: 70 nm: 10 19: Steam turbine exhaust (Condenser backpressure) 9 kPa: liquid ring vacuum pump ...
For example, USN table 6 requires 75 minutes (three periods of 20 minutes oxygen/5 minutes air) at an ambient pressure of 2.8 standard atmospheres (280 kPa), equivalent to a depth of 18 metres (60 ft). This is followed by a slow reduction in pressure to 1.9 atm (190 kPa) over 30 minutes on oxygen.
