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.

Simply to make the numbers more convenient. Each inch of water is the same as about 13.5 inches of mercury.

∙ 14y ago32 feet (384 Inches) of Water (H2O), and 29 Inches of Mercury (Hg) both equate to a perfect vacuum. From that, simple division yields 1" of water being equivalent to about 0.0739" of Mercury.

Why vacuum is important on fresh water generator?
The purpose of the vacuum in the fresh water generator it can make a 50 degrees Celsius boil the water that's why they create a
What happens to a vacuum when put in water?
it will suck the water up, depends what type of vacuum, and it could electricuit u !!! (that gd enough)
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.
Which instrument is often filled with mercury or colored water or alcohol?
Thermometers are the instrument that is often filled with mercury, colored water, or alcohol. Most early thermometers were made with mercury.
What happens when Mercury is in water?
Metallic mercury in water can be dispersed into the water column in several forms; * Metallic mercury as colloidal dispersions * Soluble mercury salts resulting from the reaction of mercury with chlorides or sulfates * Methylated mercury from the action of aquatic bacteria on metallic mercury * As a contaminant in any of the above forms on soil particles in the water Methylated mercury is easily taken up by the food chain and can accumulate in predatory fish. Eventually mercury in the water is deposited with sediments into the bottom of watercourse and will be isolated by subsequent siltation.
How many inches water equal 29.92 inches mercury?
29.92 inches of mercury = ~406.78 inches of water.
Vacuum boiling water?
vacuum is measured in inches of mercury. sea level is zero. water will boil at 212F. as negative pressure or elevation increases the boiling temp. of water decreases. if you had a pressure reading of 29.7 in" of mercury the water will boil at 192F. if you had a pressure reading of 10 in" of mercury water will boil at 32F
1.25 inches water is how many millimeters mercury?
1.25 inches of water = 2.335 mmHg
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
Why does water boil in a vacuum?
Clarification: I am wanting to know how much vacuum I need to pull to get water to boil at 150 degrees.
Is 10.3 meters of water equal to 76 meters of mercury?
10.3 meters of water is equal to 29.83 inches of mercury.
The atmospheric pressure is given as 29.4 inches of mercury what is the corresponding pressure in mm Hg?
The atmospheric pressure of 29.97 inch of mercury (32 °F) is 761.238123 millimeter Hg (0 °C) or 1.001629 atm. Scroll down to related links and use the nice calculator "Conversion of pressure or stress units".
What would be 33 ft tall if it were filled with water instead of mercury?
a manometer or vacuum gauge
How high can you lift water in a vacuum?
Roughly 16 inches before the surface starts to boil from the vacuum, this is also assuming 33 degree water, the higher the water temp the less lift will be achieved due to water's vapor pressure.
How strong is the vacuum in space?
A vacuum is nothing, an absence of any mass. There are no absolute vacuums; even in space between the planets, there is a barely measurable amount of gas, generally hydrogen gas. We expect to find that far out from the Sun, between the stars, that there is even less mass, and that in the gulfs between galaxies, there is even LESS. A vacuum has no power, no "strength". You may be trying to compare it to a vacuum cleaner on Earth, where the difference is between the "vacuum" and normal atmospheric pressure. Here on Earth, at sea level, the pressure of the atmosphere is 14.7 pounds per square inch, or "psi". A typical vacuum hose is about 1.5 inches in diameter, or with a cross-sectional area of pi*r^2, or about .75^2*3.14, or about 2 square inches. (Numbers rounded off because I'm too lazy to launch my calculator program.) So a "perfect" vacuum cleaner - capable of generating a vacuum of space - could pick up about 30 pounds, or about 3 bowling balls.
Why is it mercury rather than water used in barometer and in blood pressure measurements?
A water barometer would have to be many feet tall because the density of water is much lower than that of mercury. In addition, the vacuum above the column would be spoiled by the water vapor pressure, far higher than that of mercury, and strongly temperature dependent.
What is the general height of suction head?
since the air pressure is 14 pounds per square inch at sea level and people most often are concerned with water we can call this the concern a column of pure water 35 feet high weighs as much as the column of air extending to the perfect vacuum of space so if the pump is more than 35 feet high it will never be able to lift the water more than 35 feet the vacuum can only be perfect sea water is denser so perhaps 30 feet is that suction head mercury is a LOT denser so you can only lift that 35 inches. barometer will tell you how high the local column of air is this is called inches of mercury or mm of mercury some on else calls sea level pressure 1 atmosphere or 1 bar and divides into thousandths and calls those millibars if you have a mountain handy take a walk up there with your barometer if it says 12 inches of mercury your perfect vacuum pump can pull mercury 12 inches high or water 12' high if you bring your barometer onto a plane and the cabin isn't pressurized you may have an inch of mercury and the pump will have a suction head of one foot as a side note you can now christen your barometer an altimeter and put some new numbers on it. this is safer on the mountain than in the plane. if the weather changes and you believe the altimeter you may fly too high.. but there's an equal chance you may try to fly lower then the runway and that a bit dangerous
