How do you convert from milliliters to kilo pascals?
Milliliters belong to the volume and capacity measures. Kilopascals belong to the pressure or stress measures. One cannot be converted to the other. I do not know the correct answer. However the questioner could be referring to millimeters of mercury which is a pressure measurement and would convert to pascals.
How we convert 760 torr into 101325 newton per meter square?
760 torr is equivalent to the pressure exerted by the mass of a column of mercury that is 760 mm (or 0.76 metres) high. That is, the pressure exerted by a mass of 0.76 cubic metres of mercury on an area of one square metre. Density of mercury = 13.534 g/cm3 or 13,534 kg/m3. So mass of column of mercury = 0.76*13.534 = 10,286 kg Therefore pressure = weight of 10,286 kg/m2 = 10,286*g Newtons/m2 Now, g = 9.80665 (average of polar and equatorial values) Therefore, pressure = 10,286*9.80665 = 100,870 Newtons/sq metre. I cannot get the exact value but that may be because of rounding of "constants".
How do you convert inches Mercury to ATM?
Multiply inches of mercury by 0.033421057 to get atmospheres.
What is the Density of mercury if 23.1 cm3 has a mass of 314g?
Density = Mass/Volume ; so density = 314/23.1 => 13.5931 gcm-3 or 13.5931 g/cm3
If pressure is stated in inches that means inches of what?
Inches of mercury. It is so named because it originates from a certain pressure measurement tool that includes a column of liquid mercury.
How do you convert from Mercury to pascals?
Multiply the depth of Mercury by the density of Mercury (kg per cubic metre) and the acceleration due to gravity(m/s²)
URGENT why do you use mercury in barometers and not water?
At lower temperatures water will freeze and mercury will not.
Why is Mercury used in barometers?
In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. Other liquids can be used in barometers, but mercury is the most common because of its great density.Mainly due to its high density
Barometric pressure ground level?
Atmospheric pressure varies with altitude and air density. Average sea-level pressure is 101.325 kPa (1013.25 mbar) or 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
Why does the size of the cross-sectional area of a mercury barometer not affect the height of the enclose mercury column?
The height of the column in a mercury barometer is determined by pressure, not force. Fluid pressures depend on density and depth-pressure at the bottom of a wide column of mercury is no different than the pressure at the bottom of a narrow column of mercury of the same depth. The weight of fluid per area of contact is the same for each. Likewise with the surrounding air. Therefore barometers made with wide barometer tubes show the same height as barometers with narrow tubes of mercury.
Calculate the density of mercury if 15.0 ML weighs 204g?
To calculate the density of mercury, we need to use the formula: Density = Mass / Volume Given that the mass of 15.0 mL of mercury is 204 g, we can convert mL to L by dividing by 1000: Volume = 15.0 mL / 1000 mL/L = 0.0150 L Now we can calculate the density: Density = Mass / Volume = 204 g / 0.0150 L = 13600 g/L Therefore, the density of mercury is 13600 g/L.
As someone goes dives deeper in a ocean they have more PSI acting upon them If this ocean was mercury would the same pressure be greater or less?
Pressure in a fluid at a certain depth H is proportional to the density of the fluid. Since Mercury has a much higher density then water it will exert a much larger pressure at the same depth.
What are the measuring standards when computing density in gases?
Standar conditions for the measurement of gas density is stablished at 0°C and a pressure of 29.92 inches of mercury wich is the average pressure of the atmosphere at sea level.
Why Mercury is used in spygmomanometer?
Mercury is a heavy, silvery-white metal.Due to the high density of mercury a rise in small column of mercury can exert much pressure. so it is used to measure pressure as a small tube is sufficient to measure a considerable pressure.More over Mercury does not stick to the glass surface inside
What is mmg Hg?
mm Hg means mm of mercury (Hg comes from Hydrargyrum, Greek for watery silver(compare quicksilver), and the symbol for mercury). This represents the pressure that the height of a mercury column gives. Static pressure is defined as density x gravitational constant (approx. 9.81) x height of column. The density of mercury is 13.55 g/cm3. If the height of mercury is 760 mm, the pressure would be: 760 mmHg or 9.81x760x13.55=101023.38 N/m2 or 1010.23 mbar
What is mercury relative density?
The specific gravity of Mercury is 13.56. The density of mercury is 13.534 grams per cubic centimeter. Density is usually the ratio to the density of a given reference material.
Barometer pressure conversion from metric to imperial?
To convert kPa (which means absolutely nothing to me) to Pounds per Square Inch (P.S.I.) multiply by 0.1450377, or divide by 6.894757293. To convert P.S.I. to Inches of mercury, multiply by 2.0359281, to convert Inches of mercury to P.S.I., multiply by 0.4911765
