What else can I help you with?
Which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist.
What are the three unit of pressure equal to atmospheric sea level?
A not-commonly-used measurement is 'atmosphere'. One atmosphere is the average pressure at sea-level: 101.325 kPa, 1013.25 mbar, 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
The contour lines drawn on a 500 mb chart are lines of constant?
The contour lines on a 500 mb chart are lines of constant pressure at 500 millibars in the atmosphere. These lines connect points of equal pressure at that specific level, providing a visual representation of the pressure patterns in the upper atmosphere.
Would there be more air pressure in a balloon at sea level or high in the sky?
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
One atmosphere is equal to 100 pounds per square inch?
One atmosphere is actually equal to 14.7 pounds per square inch, not 100. This is the standard atmospheric pressure at sea level.
Which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist.
What is density altitude?
Density Altitude is the altitude relative to the standard atmosphere conditions (ISA) at which the air density will be equal to the indicated at the place of observation.

When The lower atmosphere pushes down with a force equal to two tons from what altitude?
100km
How many pounds of pressure equal one atmosphere of pressure?
One atmosphere is 14.7 psi (rounded)
What is 760 millimetres of Mercury equal to?
It is equal to 1 atmosphere or about 29.92 inches of mercury.

What is one standard atmosphere of pressure in kilopascals?
One standard atmosphere of pressure is approximately equal to 101.3 kilopascals.
What is a pressure of 101.3 equal to?
101.325 kPa is equivalent to one atmosphere of pressure, or 760 mm Hg. It is a very useful conversion factor.
What happens when a helium-filled balloon is released and rises into the atmosphere?
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
What does ATM in chemistry stand for?
ATM stands for atmosphere, such as in atmospheric pressure.
