Varies from day to day (actually, moment to moment). If you want the pressure on a particular day, a local branch of the NOAA/NWS may be able to answer that.

What is vascular pressure that declines form 35 mm Hg to 18 mm Hg?

The change in vascular pressure is a decrease of 17 mm Hg (35 mm Hg - 18 mm Hg).


An airplane is pressurized to 650 mm Hg which is the atmospheric pressure at a ski resort at 13000 ft altitude If air is 21 percent oxygen what is the partial pressure of oxygen on the plane?

To find the partial pressure of oxygen, we first need to calculate the total pressure of the air in the airplane cabin using Dalton's law of partial pressures. Given that the atmospheric pressure at 13000 ft altitude is 650 mm Hg, the partial pressure of oxygen can be calculated as 21% of this total pressure since oxygen constitutes 21% of the air. Thus, the partial pressure of oxygen on the plane is: 0.21 * 650 mm Hg = 136.5 mm Hg.


What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mm Hg and the partial pressure of helium is 439 mm Hg?

The partial pressure of hydrogen gas can be calculated by subtracting the partial pressure of helium from the total pressure. Therefore, the partial pressure of hydrogen gas would be 161 mm Hg (600 mm Hg - 439 mm Hg = 161 mm Hg).


What is 760 mm atmospheric pressure?

760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.


What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mm Hg and the partial pressure of helium is 439 Torr?

To convert Torr to mm Hg, divide by 1.33. So, the partial pressure of helium in mm Hg is 439 Torr / 1.33 = 330 mm Hg. To find the partial pressure of hydrogen, subtract the partial pressure of helium from the total pressure: 600 mm Hg - 330 mm Hg = 270 mm Hg. Hence, the partial pressure of hydrogen gas is 270 mm Hg.

If the atmospheric pressure is 24.9 inches what is the pressure in mm Hg?

To convert inches of mercury (in Hg) to millimeters of mercury (mm Hg), you multiply by 25.4. So, 24.9 in Hg * 25.4 mm/in = 632.46 mm Hg.

A barometer shows the atmospheric pressure to be 762 mm Hg What is the partial pressure of nitrogen if nitrogen is 78 percent of the air?

To find the partial pressure of nitrogen, multiply the atmospheric pressure by the percentage of nitrogen in the air (0.78). Therefore, the partial pressure of nitrogen would be 0.78 * 762 mm Hg, which equals 594.36 mm Hg.


Which one is not a unit of pressure ATM or bar or newton or mm Hg?

Newton is not a unit of pressure. Atmospheric pressure (ATM), bar, and millimeters of mercury (mm Hg) are common units of pressure.

What is atmosphoric pressure in mm hg in Colorado?

Depends on where you are in Colorado. There is no one atmospheric pressure, and it changes daily. It will be much less at the top of Mt. Evans (14,200 ft) than in Denver (5,280 ft)


How many mm Hg do you get from 0.600 ATM?

What is the atmospheric pressure if the partial pressure of nitrogen oxygen and argon are 442mm Hg 118.34mm Hg and 5.66mm Hg respectively?

These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg

A gas occupies 30 L at 760 mm Hg what is its volume at 350 mm Hg?

The phrase "760 mm Hg" is physicists' shorthand for "an atmospheric pressure equal to that needed to support a column of mercury [chemical symbol Hg] of length 760 mm". This is approximately average atmospheric pressure at sea level. As the pressure decreases from "760 mm Hg" to "350 mm Hg", the volume of the gas will increase (assuming a constant temperature). The new volume can be determined using Boyle's Law: New Volume = 30 x 760 / 350 = 65.143 Litres


What is the mean of 760mm of hg?

760 mm Hg is the standard barometric (atmospheric) pressure. It is the pressure giving a pillar of mercury (the elemental abbreviation of mercury is Hg) that is 760 millimeters (mm) high.
