if the column of water in the water barometer rose to a height of 39 feet, what would the atmospheric pressure be in mm hg?

Respuesta :

The atmospheric pressure for a column of water barometer that rose to 39 feet is 874 mmHg

From the given information, to determine the atmospheric pressure at which the column of the water barometer rose, we will need to convert the height of the water column to mmHg.

From the dimensional analysis of standard rate conversion, we know that:

1 feet  = 12 inches

1 inch = 25.4 mm

1 mmHg = 13.6 mm of water.

[tex]\mathbf{\implies 39 \ feet \ of \ H_2O \times \dfrac{12 \ in ch \ H_2O}{1 \ feet \ H_2O} \times \dfrac{25.4 \ mm \ H_2O}{1 \ inch \ H_2O} \times \dfrac{1 mmHg}{13.6 \ mm \ H_2O}}[/tex]

= 874.058 mmHg
