What gas law can be used to calculate the inflation of an airbag?
Wiki User
∙ 14y ago
n = inflated moles of gas
n= [p*V] / [R*T]
with
R = constant,
and in an airbag mostly T = constant (25 oC = 298K)
meaning:
[p1*V1] / n1 = [p2*V2] / n2

How do you calculate the amount of gas required to raise the pressure of a closed vessel to a known value?
If you know the temperature, pressure and volume of the vessel, you can calculate the amount of moles through the Ideal gas law. PV = nRT That is assuming you have ideal conditions. If not, a variance of the ideal gas law can be used in order to get the moles of your gas.
How much potassium nitrate is used in airbags?
The amount of potassium nitrate used in airbags is typically very small, usually around 100 to 200 grams. This is because potassium nitrate is used as part of a gas generator system that produces nitrogen gas to inflate the airbag very rapidly in the event of a collision. The exact amount may vary depending on the specific design and size of the airbag.
Which gas is used as reference to calculate global warming potential?
Carbon Dioxide (CO2) is given a Global Warming Potential measure of 1.There are many green house gases that cause global warming but the gas used as reference to calculate global warming potential is carbon dioxide (Co2)
How do you calculate RSD in gas chromatography?
hoe RSD calcuate in gas chromatography
How do you calculate ppm on gas chromatograph?
The same way as you would with anything else. It is merely mg per liter.
What chemical makes an airbag inflate?
The airbag's inflation system reacts sodium azide (NaN3) with potassium nitrate (KNO3 to produce nitrogen gas. Hot blasts of the nitrogen inflate the airbag.
How does sodium azide work in air bags?
The airbags inflation system reacts sodium azide with potassium nitrate to produce nitrogen gas. Hotblast of the nitrogen gas inflate the airbag.
What gas is in a bike wheel?
If you mean the gas used to inflate its tire, usually compressed air, although nitrogen gas inflation is becoming more and more common in many tire inflation applications.
What happens to an air bag during a car crash?
A accelerometer sensor on the vehicle sends a signal to the airbag to inflate when you have an accident equal to hitting a brick wall at 10-15 mph. The airbag inflation system gets the signal and this causes sodium azide to mix with potassium nitrate which produces nitrogen gas. The sudden blast of gas inflates the airbag at 200 mph. A second later the airbag deflates through tiny holes in the bag. This inflation happens in one-twenty-fifth of a second. The powdery substance left is cornstarch or talcum powder use to keep the bag pliable and lubricated during storage.
Why does an airbag inflate?
Gas is created, increasing n; and The added gas increases the pressure and then the volume of the airbag. for my fellow cheaters out there
How is airbag inflated?
The sensor is the device that tells the bag to inflate. Inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 km per hour). A mechanical switch is flipped when there is a mass shift that closes an electrical contact, telling the sensors that a crash has occurred. The sensors receive information from an accelerometer built into a microchip.The airbag's inflation system reacts sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas. Hot blasts of the nitrogen inflate the airbag.
What gas filles up an airbag?
me not know me neither
What s the gas that inflates the airbag?
Primarily compressed nitrogen as it is unreactive. Nitroguanidine (also used as insecticide and to start high energy reactions) is sometimes used.
What is inside a airbag when deployed?
The airbag contains sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas. Hot blasts of the nitrogen inflate the airbag.
Since 1970 have gas prices risen with the same inflation rate as other prices like milk or shampoo?
No they have risen because of the increasing lack of availability of oil which is used to make gas. Each curency will have a different inflation rate. The dollar maybe see 5%, rubble maybe 10%, and so on. They all have different inflation rates.
Will incorrect tire inflation cause bad gas mileage?
bad gas mileage
Where is the airbag module on a vw cabrio?
Right next to the gas pedal
