The pressure ( P ) at any depth ( d ) is given by the equation: P = ρgd P = ρgd. Where ρ (“rho”) is the density of the liquid and g is the acceleration due to gravity (on Earth, g = 9.81 m/s 2 ). The density of water at 20 °C is ρ = 998 kg/m 3, but generally the calculations are greatly simplified if you assume a temperature of 4 °C ...Sea level atmospheric pressure will support a mercury column generally not more than 29.92-in. high. Thus, the standard for atmospheric pressure at sea level is 29.92 in.-Hg, which translates to an absolute pressure of 14.69 psia. The two basic reference points in all these measurements are standard atmospheric pressure and a …Dallas/Fort Worth - Monthly Pressure Records Note: The above pressures are corrected to sea level.
