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

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.

What are the units used to measure blood pressure?

Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of Mercury (mm Hg).


Why water cannot be used in simple barometer?

Following are the reasons why mercury and not water is used in a barometer:1. Mercury is relatively denser than water, consequently the length of the column of water would have to be about 34 feethigh to exert pressure equal to that of the atmosphere while the column of mercury need to be only 30 inches to exert pressure equal to that of the atmosphere.2. Mercury has a very low vapor pressure when compared to that of water. So it is more sensitive than water to the changes in the atmospheric pressure and rises more quickly to record the changes in the atmospheric pressure.3. Mercury's freezing point is much lower than that of water's so it can record the atmospheric pressure at temperatures below that of 0 degrees centigrade.4. Mercury does not evaporate easily so very little mercury vapor enters the vacuum above the mercury in the tube.5. Mercury being a metal shines brightly and so can be used to read the markings on the tube easily.

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?

The common method to measure atmospheric pressure employs an inverted column submerged in a fluid to determine the level at which the column has to be raised to equalize the external atmospheric pressure and the internal column pressure. The height at which the fluid inside the column ceases to increase is correlated to atmospheric pressure. Due to mercury's high density, this level is on the order of inches (~30 inches of mercury at atmospheric pressure). If water were to be used the column would have to be ~32 feet tall in order to develop the equalized pressures between the column and atmosphere.


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.

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.
