Atmospheric pressure is the weight of the air above you. this weight is 14.7 lbs per square inch at sea level. Air is made up of 78% Nitrogen - 21% oxygen and 1% trace gasses at sea level, This changes as you ascend as oxygen thins out and other gasses take its place which are lighter than air this changes the partial pressures of the gasses and of cores the weight.
What else can I help you with?
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
Where on earth is atmospheric pressure greatest?
The atmospheric pressure is greatest at sea level, which is at the Earth's surface. As altitude increases, atmospheric pressure decreases.
What is the symbol for an atmospheric pressure of 1076 millibars and steady?
he symbol for an atmospheric pressure of 1076 millibars and steady. State the letter of the correct answer.
What is the physical state of argon at -197 and normal atmospheric pressure?
Argon will be a gas at -197°C and normal atmospheric pressure, as it has a boiling point of -185.8°C at atmospheric pressure.
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
Rain typically occurs in low atmospheric pressure systems where air rises, cools, and condenses to form clouds and precipitation. High atmospheric pressure systems typically bring stable and clear weather conditions with less likelihood of rain.
Does gauge pressure include atmospheric pressure?
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
What is the difference between gauge pressure and atmospheric pressure?
Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
Does atmospheric pressure increase with altitude?
No, atmospheric pressure decreases with altitude.
What is the difference between gage pressure and absolute pressure, and how do they affect the measurement of pressure in a system?
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure. Gage pressure only considers the pressure above atmospheric pressure, while absolute pressure includes atmospheric pressure as well. This affects pressure measurements in a system because gage pressure readings will fluctuate with changes in atmospheric pressure, while absolute pressure readings will remain constant regardless of atmospheric pressure changes.
To change from psig to psia you must add what to p.s.i.g?
You must add the atmospheric pressure.
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)
Is gauge pressure is the sum of true pressure and atmospheric pressure?
No, it is the DIFFERENCE between the true and atmospheric pressures.
What does absolute pressure include that gauge pressure does not?
abosulute pressure includes the atmospheric pressure while gage pressure gives the pressure above atmospheric pressure
Where on earth is atmospheric pressure greatest?
The atmospheric pressure is greatest at sea level, which is at the Earth's surface. As altitude increases, atmospheric pressure decreases.
What is the Significance of atmospheric pressure?
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
