In this episode, the Roswell Flight Test Crew helps you prepare for your Part 107 pilot's test by teaching you how to calculate pressure altitude: the altitude your aircraft “feels” like it's flying at, based on its elevation above sea level as well as the local atmospheric pressure. Atmospheric pressure drops as altitude increases, making airfoils, like wings and propellers, less efficient. However, atmospheric pressure is also affected by high pressure and low pressure weather systems. This is reflected in the local barometric pressure reading, measured in inches of mercury and also referred to as the altimeter setting. By reference the local altimeter setting and the density altitude chart, you can determine your pressure altitude.

Topic: Atmospheric Pressure
Why don't we get crushed by atmospheric pressure?
Hey. Did you hear that?
His ears popped.
Is this related to atmospheric pressure?
Yes.
We know that our earth is surrounded by a layer of air called the atmosphere.
The gravitational force of earth constantly pulls this atmosphere towards itself.
Due to this, the atmosphere exerts a pressure on the surface of the earth as well as on the objects present on its surface.
This pressure exerted by the atmosphere is called the atmospheric pressure.
This atmospheric pressure outside our body is balanced by the air pressure present inside our body.
When the atmospheric pressure decreases, it becomes less than the air pressure inside us.
Now, to balance the pressure inside and outside our ears, the air present inside rushes out.
Whereas, when the atmospheric pressure increases, it becomes more than the air pressure inside us.
So, to balance the pressure inside and outside our ears, the outside air rushes in.
This movement of air results in that sudden pop.
Have you noticed this before?
Has your water bottle ever got crushed once your airplane landed?
This happens because of changes in the atmospheric pressure.
Generally, the atmospheric pressure in the bottle is equal to that on the surface of the earth.
Whereas, in an airplane the atmospheric pressure is low as compared to that on the surface of the earth.
During the flight, when you open the bottle and drink some water in the airplane, the atmospheric pressure in the bottle becomes low.
This is because the low pressure air present in the airplane occupies the place of water which you just drank.
However, when the airplane lands and you come out of the plane, the pressure outside the bottle, that is, the atmospheric pressure on the surface of earth is high as compared to the pressure inside the bottle.
Hence, the outside air exerts a greater pressure on the surface of the bottle than the inside air.
As a result, the bottle gets crushed.
Wow. How is he able to lift such a heavy car?
Are we also powerful enough to handle such a huge amount of pressure?
Yes, to some extent we are also carrying a huge amount of pressure.
At sea level, the atmospheric pressure is about 14.7 psi.
This means that the atmosphere is exerting 14.7 pounds of force on every square inch of our body which is really huge.
So, why don't we feel this immense pressure?
This is because various parts of our body such as ears, nose, lungs and stomach also contain air which exerts pressure on the atmosphere which is equal to the atmospheric pressure.
In this way, the atmospheric pressure and the air pressure present inside our body cancel each other.
As a result, we don't get crushed by the atmospheric pressure.

"Atmospheric pressure" is the pressure exerted by the weight of air in the atmosphere of Earth . In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. On a given plane, low-pressure areas have less atmospheric mass above their location, whereas high-pressure areas have more atmospheric mass above their location. Likewise, as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation. On average, a column of air one square centimeter in cross-section, measured from sea level to the top of the atmosphere, has a mass of about 1.03 kg and weight of about 10.1 N . Atmospheric pressure is sometimes called barometric pressure.
The standard atmosphere is a unit of pressure equal to 101325 Pa or 1013.25 hectopascals or millibars. Equivalent to 760 mmHg , 29.92 inHg, 14.696 psi.
The mean sea level pressure is the atmospheric pressure at sea level or the station pressure adjusted to sea level assuming that the temperature falls at a lapse rate of 6.5 K per km in the fictive layer of air between the station and sea level.
This is the atmospheric pressure normally given in weather reports on radio, television, and newspapers or on the Internet. When barometers in the home are set to match the local weather reports, they measure pressure adjusted to sea level, not the actual local atmospheric pressure.

The molecules leaving a liquid through evaporation create an upward pressure as they collide with air molecules. This upward push is called the vapor pressure.
Different substances have different vapor pressures and therefore different boiling points. This is due to differing intermolecular forces between molecules.
The vapor pressure of a liquid lowers the amount of pressure exerted on the liquid by the atmosphere. As a result, liquids with high vapor pressures have lower boiling points.
Vapor pressure can be increased by heating a liquid and causing more molecules to enter the atmosphere. At the point where the vapor pressure is equal to the atmospheric pressure boiling will begin. In effect, without any external pressure the liquid molecules will be able to spread out and change from a liquid to a gaseous phase. The gas, as bubbles in the liquid, will rise to the surface and be released into the atmosphere.

A manometer (not to be confused with nanometer) is a good example, as it uses a column of liquid to both measure and indicate pressure. Likewise the widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge.
Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure ) is a principle in fluid mechanics that states that pressure at a point, has infinite direction, and thus a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. The law was established by French mathematician Blaise Pascal in 1647–48.
What is the value for atmospheric pressure?
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103dynes per square centimetre,1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
What is atmospheric pressure on human body?
Yes, to some extent we are also carrying a huge amount of pressure. At sea level, the atmospheric pressure is about14.7 psi. This means that the atmosphere is exerting 14.7 pounds of force on every square inch of our body which is really huge.
What is considered low atmospheric pressure?
When the air pressure drops, so does the mercury level."Atmospheric pressure can also be measured in millibars (mb), with a "bar" being roughly equivalent to one atmosphere ofpressure (one atmosphereequals 1.01325 bars). One bar is equivalent to 29.6 in. Hg.A barometer reading of 30 inches (Hg) is considered normal.
What is the definition of pressure in science?
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... Absolute pressure of a gas or liquid is the total pressure it exerts, including the effect of atmospheric pressure. An absolute pressure of zero corresponds to empty space or a complete vacuum.
What is the simple definition of pressure?
Pressure means how much something is pushing on something else. It is expressed as force per unit area: P=F/A. In technology, pressure is often specified in multiples of atmospheric pressure. It can also be defined as the thrust [compressive force acting perpendicularly to the surface of a body] acting per unit area.
What is called pressure?
pressure. Posted by: Margaret Rouse. Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared (N/m 2 or N.
What are 5 units of pressure?

How do you calculate the pressure?
Pressure and force are related, and so you cancalculate one if you know the other by using the physics equation, P = F/A. Becausepressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.

What are some examples of pressure?
Examples of fluid motion because of pressure include breathing, and air currents (weather). When you breathe in, you move a diaphragm that lowers the pressure inside your lungs. Higher pressureair outside your body is sucked into the lungs to fill the gap. Sea and land breezes work similarly.
How do you calculate water pressure?
Find Water Pressure of Upright Cylinder. Determine the water pressure at the bottom of a full, upright cylinder by dividing the volume by the product of pi (?) multiplied by radius squared (R^2): V = ?R^2. This gives the height. If the height is in feet, then multiply by 0.4333 to get pounds per square inch (PSI).
How do you calculate hydrostatic pressure?
The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculatedusing the hydrostatic equation: P = rho * g * d, where P is thepressure, rho is the density of the liquid, g is gravity (9.8 m/s^2) and d is the depth (or height) of the liquid.

This chemistry video tutorial provides a basic introduction into vapor pressure. Vapor pressure is the partial pressure at which a substance's rate of evaporation is equal to the rate of condensation. This tutorial explains how to calculate the vapor pressure and normal boiling point of a substance using the clausius clapeyron equation. The normal boiling point is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure at sea level. Vapor pressure increases with temperature. The boiling point of a substance is inversely related with elevation. Substances with high intermolecular forces tend to have a high boiling point and a low vapor pressure. Intermolecular forces included in this tutorial are london dispersion forces and hydrogen bonds - a special kind of dipole dipole interaction.

Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure ) is a principle in fluid mechanics that states that pressure at a point, has infinite direction, and thus a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. The law was established by French mathematician Blaise Pascal in 1647–48.
What is the value for atmospheric pressure?
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103dynes per square centimetre,1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
What is atmospheric pressure on human body?
Yes, to some extent we are also carrying a huge amount of pressure. At sea level, the atmospheric pressure is about14.7 psi. This means that the atmosphere is exerting 14.7 pounds of force on every square inch of our body which is really huge.
What is considered low atmospheric pressure?
When the air pressure drops, so does the mercury level."Atmospheric pressure can also be measured in millibars (mb), with a "bar" being roughly equivalent to one atmosphere ofpressure (one atmosphereequals 1.01325 bars). One bar is equivalent to 29.6 in. Hg.A barometer reading of 30 inches (Hg) is considered normal.
What is the definition of pressure in science?
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... Absolute pressure of a gas or liquid is the total pressure it exerts, including the effect of atmospheric pressure. An absolute pressure of zero corresponds to empty space or a complete vacuum.
What is the simple definition of pressure?
Pressure means how much something is pushing on something else. It is expressed as force per unit area: P=F/A. In technology, pressure is often specified in multiples of atmospheric pressure. It can also be defined as the thrust [compressive force acting perpendicularly to the surface of a body] acting per unit area.
What is called pressure?
pressure. Posted by: Margaret Rouse. Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared (N/m 2 or N.
What are 5 units of pressure?

How do you calculate the pressure?
Pressure and force are related, and so you cancalculate one if you know the other by using the physics equation, P = F/A. Becausepressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.
What is a pressure in science?
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... Absolutepressure of a gas or liquid is the total pressure it exerts, including the effect of atmospheric pressure.
What are some examples of pressure?
Examples of fluid motion because of pressure include breathing, and air currents (weather). When you breathe in, you move a diaphragm that lowers the pressure inside your lungs. Higher pressureair outside your body is sucked into the lungs to fill the gap. Sea and land breezes work similarly.
How do you calculate water pressure?
Find Water Pressure of Upright Cylinder. Determine the water pressure at the bottom of a full, upright cylinder by dividing the volume by the product of pi (?) multiplied by radius squared (R^2): V = ?R^2. This gives the height. If the height is in feet, then multiply by 0.4333 to get pounds per square inch (PSI).
How do you calculate hydrostatic pressure?
The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculatedusing the hydrostatic equation: P = rho * g * d, where P is thepressure, rho is the density of the liquid, g is gravity (9.8 m/s^2) and d is the depth (or height) of the liquid.

https://mocomi.com/ presents: How does a pressure cooker work?
The laws of Physics apply to our everyday activities, even cooking food. Watch this animated video explaining how a pressure cooker works to cook our food faster.
Steam and Pressure are 2 very important things happening inside the chamber of a pressure cooker.
A pressure cooker is made up of a pot, a lid which fits precisely on the pot with a locking mechanism; a rubber ring that goes between the lid and the pot so that no air can escape; a valve on top of the lid with a release whistle
There are 2 extremely important parts in all pressure cookers. The rubber ring that goes between the pot and the lid ensures that no air escapes from inside the container; if it did then the pressure would not be able to build up.
The valve on the top is a safety measure that makes sure the pressure does not build up to dangerous levels inside the pot. This could lead to a potentially dangerous explosion. It is designed to allow some of the steam to escape after the pressure inside reaches a certain point. And with that startling whistle we know how much the food has been cooked.
