One bar is atmospheric pressure at sea level.
Before an aircraft leaves the ground the control tower gives the pilot an adjustment that depends upon the local atmospheric pressure and by how much it deviates from normal sea level pressure so that the pilot can adjust his altimeter. The altimeter registers atmospheric pressure and reads out in feet of altitude. As the aircraft climbs the pressure diminishes and the altimeter dial shows and increasing reading in feet. The opposite as it descends. When a light aircraft lands in poor visibility it is fairly important that the altimeter is reading correctly, hence the need to adjust it to local 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.
A pressure difference is also known as an?
A pressure difference is also known as a pressure gradient.
Can station pressure ever exceed sea level pressure?
No, station pressure represents the actual atmospheric pressure at a specific location, while sea level pressure is adjusted for elevation. Sea level pressure can be higher than station pressure due to the effect of elevation on atmospheric pressure, but station pressure cannot exceed sea level pressure.
Wind blows out of low pressure areas?
No, it blows into low pressure areas. Air moves from areas of high pressure to low pressure.
Winds are generated when air flows from a high pressure area into a what?
Winds are generated when air flows from a high pressure area into a low pressure area. This movement occurs due to the pressure difference, with air moving from areas of higher pressure to lower pressure to equalize the pressure gradient.
What is the atomospheric pressure on venus?
92 Times heavier then earths
What height in the atmosphere would atomospheric pressure be 1.0 millibars?
320,000 ft above sea leavel
Why does the weather behind the cloud fronts tends to clear because?
because the atomospheric pressure has increased which does not allow many clouds to form
When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
Which term is defined as the atomospheric pressure at sea level at zero degress celsius?
The term you're looking for is "standard atmospheric pressure," which is defined as the atmospheric pressure at sea level at zero degrees Celsius. It is commonly used as a reference point for pressure measurements in meteorology and other fields.
What is carbon two forms?
Oxidized carbon as atomospheric CO2 and Varbonate rock in limestone.
What atomospheric layer is least dense?
Basically, the higher you get in the atmosphere, the less dense it gets. It's the exosphere.
What is gauge pressure?
From a nursing perspective... The gauge of the needle tells us the size of the lumen (inside) of the tube. Size 18 is big whilst size 30 is small. If we want a substance that we're injecting to have low pressure (ie if cleaning a wound with saline and not wanting it to hurt or disturb the healing and using a syringe to apply it) then we use a large size (ie 16). Hope this helps Gauge pressure is the pressure recorded on the gage that records above the atmospheric pressure. Normal atomospheric pressure is 14.7psi. So if a gage read 10 psi of gage pressure, then the true pressure would be 24.7 psi. Hope this is right.
How does paint stop rust?
Rusting is caused due to exposture of iron to moisture. When iron articles are painted, it is not exposed to the atomospheric moisture. This is how paint stops rusting
Why do balloons let air out?
Balloon is made up of elastic material. It is blown because of pumping air into it. Now the wall of the balloon gets stressed. Stress is nothing but the deforming force per unit area. Same way pressure is also the force per unit area. Hence the pressure inside the ballon would increase and become greater than the atomospheric pressure. So, as we allow the mouth to be in open condition, the air rushes out from higher pressure region to lower pressure region.
What happens to energy at its boiling point?
They make the water into steam. Part of it is transferred into latent heat, which is heat water requires to become steam. As you keep heating the water (assuming it's a closed flask), then eventually all the water will become steam.
What is the boiling point of a compound?
as far as i know the B.Pt. is defined as " when the vopour pressure of the liquid is equal to the atomospheric pressure then it is said to be the boiling point of the liquid." similarly "when the vapuor pressure of the solid is equal to atmospheric pressure then its corresponding temperature is called melting point of that compound." so a compound may be a low melting one but the same compound may be ahigh boiling liquid. this is due to the inter & intra molecular forces that exists in the molecules. so there is no specific equation that a compound having a m.p. of 102c will have a b.pt. of some particular value.
