How does barometric pressure vary with altitude?
pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.
How does barometric pressure affect gauge pressure?
Assuming we are using a pressure transducer to measure barometric pressure, I understand that a gauge type transducer would be used. The internal diaphragm would have a fixed pressure behind it (at a guess would be at standard temp/pressure, STP, ie 20 deg C @ 1013mb), so the transducer has a reference to work against. The front of the diaphragm would be exposed to atmosphere. I would assume the reference (gauge) pressure would vary as the barometric pressure varies, as the diaphragm would move towards the side with least pressure, or at 1013mb the diapragm would be in the centre (which could be used as the null output voltage), higher than 1013mb could produce a positive voltage swing, less than 1013mb could go negative. This is all I can think of, please let me know if on the right track.
How does increasing pressure in a chamber help treat the bends?
Spending time in a barometric chamber (in which the pressure is raised above atmospheric) causes nitrogen bubbles in the blood stream (the cause of the bends) to go back into solution and gives the nitrogen the opportunity to exit the body via the lungs so that it won't come back out of solution when the pressure is lowered.
How is air pressure related to altitude?
The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
How does liquid pressure vary with depth?
The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10 meters) you go down, the pressure increases by 14.7 psi (1 bar). In the deepest ocean, the pressure is equivalent to the weight of an elephant balanced on a postage stamp, or the equivalent of one person trying to support 50 jumbo jets!
Does barometric pressure go up or down in high altitudes?
Should you be flying does barometric pressure go up or down
How does barometric pressure change with altitude?
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
What does up when the rain comes down?
If you mean what 'goes' up when the rain comes down, then the answer is the barometric pressure. A low pressure cell, which is a chief indicator of a rain storm, occurs when the barometric pressure drops below 30 points. As the storm dissipates, the low pressure cell changes, causing the barometric pressure to rise.
Can tornadoes go down hills?
yes
What is atmospherical pressure at higher and lower altitude?
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)

How does density of an object relate to the pressure it exerts?
The further down you go the more pressure is exerted upon that point by the sum of the weight ( gravity and density) of the substance (usually water) above that point (the height or depth). For example, if their where say more argon than there is now in the atmosphere the barometric pressure would be higher when ignoring the changes in pressure due to weather.
Can a tornado go uphill?
Yes. Tornadoes can go up and down hills largely unhindered.
Where can you find the high and low barometric pressure for yesterday?
wunderground.com If you type in your area and go to history you'll see all that weathery information for every day of the year.
Does pressure decrease or increase in the ocean?
Pressure increases as you go down.
Why does pressure go up when you go down?
Pressure depends mainly upon the weight of fluids (like air or water) that is above you, being pulled downward by gravity. When you go up, there is less fluid above you and less pressure; when you go down, there is more fluid above you pushing down and more pressure.
Where does low pressure go in the atmosphere?
down
