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)
A closed end manometer has a U tube with a sample of hydrogen gas in the bulb The difference in the height of the columns of mercury is 18.0 cm What is the pressure of the hydrogen gas in torr?
To find the pressure of the hydrogen gas in torr, you can use the difference in height of the mercury columns and the density of mercury. First, calculate the pressure difference due to the 18.0 cm height difference in the mercury columns. Then, convert this pressure into torr using the conversion factor 1 atm = 760 torr.
Why is Mercury used in barometers?
Mercury is used in barometers because it is a dense liquid at room temperature, making it ideal for measuring atmospheric pressure. Its high density allows for a clear and precise reading of pressure changes, as the column of mercury inside the barometer moves up and down in response to changes in air pressure. Mercury also does not adhere to glass, allowing for an accurate indication of pressure levels.
Does mercury exert more pressure than water?
Yes, mercury exerts more pressure than water due to its higher density and heavier weight. This is why a barometer, which uses mercury, is able to measure atmospheric pressure accurately.
URGENT why do you use mercury in barometers and not water?
Mercury is used in barometers because it has a high density, does not evaporate easily, and has a low thermal expansion. These properties make it ideal for creating a precise and stable measurement of atmospheric pressure. Water, in contrast, would evaporate easily and change density with temperature, making it less reliable for this purpose.
How do you measure psi with inches of Mercury?
You can convert inches of Mercury (inHg) to pounds per square inch (psi) by dividing the inHg value by 2.036. This conversion is based on the relationship between pressure in units of inches of Mercury and pounds per square inch.
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 kind of liquid is found in a barometer?
Mercury is the liquid typically found in a barometer. It is used to measure atmospheric pressure due to its density and ability to rise and fall within the tube as pressure changes.
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.
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
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 mercury column in a barometer is determined by the pressure of the atmosphere pushing down on the mercury in the dish, rather than the cross-sectional area of the barometer tube. This height is a result of balancing the weight of the mercury with the atmospheric pressure. Changing the cross-sectional area would only affect the amount of mercury needed to create this balance, not the height of the column.
