Best Answer

The density of Mercury is 13.534, compared to '1' for water. So the water column

is 13.534 times as high as the mercury column at the same pressure.

(30 inches of water) x (25.4 millimeters/inch) / 13.534 = 56.3 millimeters of mercury

What is the conversion of vacuum in inches of water to vacuum in inches of mercury?

There's no such thing as "mercury vacuum". A volume of space can have solid mercury, liquid mercury, or mercury vapor in it, or it can be a vacuum. The weight of the "standard atmosphere" on any area is the same as the weight of a column of mercury 29.92 inches high on that same area, with no air above the mercury.


Whether mmof water column unit is higher unit then mm of hg?

since mercury (Hg) is much more dense than water, x mm of Hg is a higher pressure than x inches of water column (in wc) or x mm of water column.Inches of water and millimeters of mercury are both the measure of pressure by equating the pressure to a height of a column of fluid (pressure-fluid height relationship) and thus, the density of the fluid greatly affects the pressure measurement.


What is 0.5 psig in inches of water column?

0.5 psig is equivalent to 13.8 inches of water column.


How many inches water equal 29.92 inches mercury?

To convert inches of mercury to inches of water, you can use the conversion factor of 1 inch of mercury = 13.6 inches of water. Therefore, 29.92 inches of mercury is equal to 29.92 x 13.6 = 407.552 inches of water.


Why is the value of atmospheric pressure compared to mercury?

Atmospheric pressure will support a column of mercury to about 760 mm. Mercurial air pressure is described as '760 mmHg'. As air pressure changes , the height of this column will also change. If you did it with water, the column would have to be about 34 feet (10.2 metres) in height.


7 inches water column equal how many PSI?

1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.

What is the unit to measure atmospheric pressure?

There are several units in common usage. In the US they like "inches of mercury" and "Paschals." Industrial types (especially those dealing in steam) like inches of WC (water column). Scientists like me prefer to use millimeters of mercury, or "atmospheres" (1 ATM= 760 mm Hg = 1 Torr). Take your pick!


How do you convert inch of water column to volume?

To convert inches of water column to volume, you would need to know the area over which the water column is acting. Once you have the area, you can calculate the volume by multiplying the inches of water column by the area in square inches. The formula would be: Volume = Inches of water column * Area.


How much psi is 35 inches of water?

35 inches of water is equivalent to approximately 1.27 psi. This can be calculated by dividing the height of the water column (35 inches) by the conversion factor (27.71 inches of water column per psi).
