What else can I help you with?
How does the atmospheric pressure below sea level compare with atmospheric pressure at sea level?
It is greater.
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
How much air pressure is on you if i'm below sea level?
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
What is the atmospheric pressure at sea level in pascal?
The atmospheric pressure at sea level is approximately 101,325 pascals.
Does atmospheric pressure still exert a force on you when you are under water?
Atmospheric pressure exerts more force on you if you are deeper than 10 meters. At 10m below sea level the atmospheric pressure is double that of on land and it increase with every 10 metres that you descend
How does atmospheric pressure change with height above sea level?
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
Is atmospheric pressure higher on a mountain or sea level?
The answer is sea level. Because atmospheric pressure decreases when altitude increases
What is a mercury barometer used for?
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
What are the uses of mercury barometers?
Mercury barometer is used for measuring atmospheric pressure.Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.Read more: Uses_of_mercury_barometer
The pascal is a metric unit for measuring what?
A pascal is a measurement of pressure, equal to one Newton per square metre. To compare, atmospheric pressure at sea level is 101325 pascals. ■
What is the atmospheric pressure gauge pressure and absolute pressure and relation between them?
Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere, typically measured at sea level and approximately equal to 101.3 kPa (kilopascals) or 1 atm. Gauge pressure is the pressure measured relative to atmospheric pressure, meaning it excludes atmospheric pressure from its measurement; it can be positive or negative depending on whether the pressure is above or below atmospheric pressure. Absolute pressure, on the other hand, is the total pressure measured relative to a perfect vacuum, and is calculated by adding atmospheric pressure to gauge pressure. The relationship can be expressed as: Absolute Pressure = Gauge Pressure + Atmospheric Pressure.
Why vacuum pressure is negative?
Vacuum pressure is negative because it is measured relative to atmospheric pressure, which is considered the reference point of zero pressure. When the pressure in a system drops below atmospheric pressure and leads to a vacuum, the pressure is expressed as negative to indicate the lower pressure level in comparison to the reference point.
