Atmospheric pressure is the force exerted by the weight of the air above a given point. Five applications for atmospheric pressure include weather prediction, operating barometers and altimeters, supporting combustion in fires, powering pneumatic tools, and facilitating the movement of air in ventilation systems.

What temperature would water boil at if the pressure was 5 psi absolute pressure?
At 5 psi absolute pressure, water would boil at approximately 165°F (74°C). This is lower than the normal boiling point of water at standard atmospheric pressure (212°F or 100°C) because the lower pressure reduces the boiling point of the water.
How much pressure does your brain exert on your skull?
The pressure exerted by the brain on the skull is called intracranial pressure, which typically ranges from 5 to 15 mmHg in adults. This pressure provides essential cushioning and support for the brain within the skull while maintaining proper blood flow. Any significant increase in intracranial pressure can indicate underlying health issues that may require medical attention.
What is the difference between gauge pressure and absolute pressure?
Absolute pressure = gauge pressure + atmospheric pressureWhen using a pressure gauge, like when measuring the pressure of the air in a tire, the gauge is actually reading the difference between the atmospheric pressure and the atmospheric pressure. So if the gauge measures 30 psi, and taking atmospheric pressure at about 14.7 psi, the absolute pressure in the tire is actually about 44.7 psi. If the tire is flat, then the gauge will read zero psi, but there is not a vacuum - there is still some air present in the tire, and the absolute pressure of this air is the same as the atmospheric pressure (about 14.7 psi).See related link: Guide to the Measurement of Pressure and Vacuum.
What are some of the examples of atmospheric pressure?
Examples of atmospheric pressure include the weight of the air pressing down on the Earth's surface, which is around 14.7 pounds per square inch at sea level. Atmospheric pressure is also responsible for creating weather patterns and influencing the behavior of gases in our atmosphere.
Why water cannot be used in simple barometer?
Water is not suitable for use in a barometer because it is too dense and heavy, which would require a very tall column to measure small changes in atmospheric pressure accurately. Additionally, water can easily evaporate and create inaccuracies in the measurements. Mercury is traditionally used in barometers because it is dense, does not easily evaporate, and provides a more practical measurement system.
What period of time do boiling eggs get ready?
Depending on the atmospheric pressure where you live, 5-30 minutes.
Why is the atmospheric pressure at the top of mt Everest 5 lbin squared much less than the atmospheric pressure here on earth 14.7 lbin squared?
The atmospheric pressure decreases with increasing altitude because there is less air above pushing down on the air at higher altitudes. Mount Everest is much higher in altitude compared to places on Earth where the pressure is measured at 14.7 psi. As you go higher up, the weight of the air above becomes less, leading to lower atmospheric pressure.
How much lift is exerted on the wings of an airplane that have a total surface area of 108 m when the difference in air pressure below and above the wings is 5 percent of atmospheric pressure?
The lift on the wings of the airplane can be calculated using the formula: lift = pressure difference * wing area. Given that the pressure difference is 5% of atmospheric pressure, and atmospheric pressure is about 101325 Pa, the pressure difference is 0.05 * 101325 = 5066.25 Pa. Therefore, the lift exerted on the wings is 5066.25 * 108 = 547170 N.

What temperature would water boil at if the pressure was 5 psi absolute pressure?
At 5 psi absolute pressure, water would boil at approximately 165°F (74°C). This is lower than the normal boiling point of water at standard atmospheric pressure (212°F or 100°C) because the lower pressure reduces the boiling point of the water.
How high can you suck water up a straw if The pressure in the lungs can be reduced to about 5 kPa below atmospheric pressure?
With the pressure in the lungs reduced to 5 kPa below atmospheric pressure, you can theoretically suck water up a straw to a maximum height of about 5.1 meters. This is because atmospheric pressure can support a water column of approximately 10.3 meters at sea level, and reducing the pressure in the lungs allows you to lift the water to half that height.
5 weather instrument draw and give its function uses?
Thermometer: Measures the temperature of the atmosphere. Anemometer: Measures wind speed and direction. Barometer: Measures atmospheric pressure to help forecast weather changes. Hygrometer: Measures humidity in the air. Weather vane: Indicates the direction from which the wind is blowing.
What pressure should the low pressure port be on a 2001 Chevy blazer?
It will depend on the outside air temp, but 35 give or take 5 is a good place to start.

Why is there more air pressure in the first layer of atmosphere?
The atmosphere consists of 5 layers: the troposphere, which we live in; followed by stratosphere, mesosphere, thermosphere and exosphere. Air pressure at any of these layers is typically caused by hydrostatic pressure, defined as P = hpg, where P is the pressure, h is the height or depth of fluid, and g is the gravitational acceleration. In simple context, my physics lecturer once explained to me: the reason why we live under an atmospheric pressure of 1 bar is simply because there is a column of air above us. As we move upwards (e.g. in an airplane or on top of a mountain), the height of this column is reduced, thus the atmospheric pressure is less. Therefore, the first layer of atmosphere (or the lowest layer) will experience the highest air pressure.
How much pressure does your brain exert on your skull?
The pressure exerted by the brain on the skull is called intracranial pressure, which typically ranges from 5 to 15 mmHg in adults. This pressure provides essential cushioning and support for the brain within the skull while maintaining proper blood flow. Any significant increase in intracranial pressure can indicate underlying health issues that may require medical attention.
How do you calculate absolute pressure at 55 metres below sea level when atmospheric pressure is 103 kilo pascals?
absolute pressure of liquid = atmospheric pressure (P₀) + (relative density (ρ) of liquid x height of liquid x gravitational acceleration) P₀ = 103000 Pa ρ of sea water at 15°C = 1025 kg/m³ h = 55 m g = 9.81m/s² Answer = 103000 Pa + (1025 kg/m³ x 9.81 m/s² x 55 m) Answer = 6.56 x 10^5 Pa (Sorry about using the carat in signifying the scientific notation, but apparently I cannot find a way to type a superscript 5 using code.)
