Negative inches of water column (inches of vacuum) represent the pressure below atmospheric pressure. For example, -1 inch of water column indicates a vacuum that is 1 inch lower than atmospheric pressure. In general, the more negative the inches of water column, the stronger the vacuum. Thus, -10 inches of water column corresponds to a vacuum of 10 inches below atmospheric pressure.

What is minus 2 inch of water in vacuum equal to how many inch of hg?

Minus 2 inches of water in a vacuum is equivalent to approximately 0.73 inches of mercury (inHg). This conversion is based on the fact that 1 inch of water is roughly equal to 0.0361 inches of mercury. Therefore, to convert -2 inches of water to inches of mercury, you multiply by this conversion factor, resulting in a negative pressure measurement in inches of mercury.


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 many inches of water column equal 5 psi?

To convert psi (pounds per square inch) to inches of water column, you can use the conversion factor that 1 psi is approximately equal to 27.7 inches of water column. Therefore, 5 psi is equal to about 5 x 27.7, which equals approximately 138.5 inches of water column.


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).


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.

What is 30 inches water column in millimeters mercury?

The density of mercury is 13.534, compared to '1' for water. So the water columnis 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
