At a pressure of 885 mbar
, what would be the corresponding height of the mercury in the column of a mercury barometer?
The height of the mercury in a barometer is directly proportional to the atmospheric pressure. The standard atmospheric pressure at sea level corresponds to a mercury column height of 760 mm or 760 mbar.
Given that the pressure is 885 mbar, we can use the ratio of pressures to find the corresponding height of the mercury column:
Height of mercury column = (Pressure / Standard pressure) * Standard height
Height of mercury column = (885 mbar / 760 mbar) * 760 mm
Height of mercury column = 1.164 * 760 mm
Height of mercury column ≈ 884.6 mm
Therefore, at a pressure of 885 mbar, the height of the mercury in the column of a mercury barometer would be approximately 884.6 mm.
