KLoux said:You may need to consider things like temperature, too - Google the Ideal Gas Law and read about the assumptions made for an Ideal Gas, then search for the Combined Gas Law, which is really probably what you're looking for.

To calculate the pressure of air in a cylinder, you can use the formula: P = F/A, where P is the pressure, F is the force exerted on the air, and A is the area of the cylinder's cross-section. You can also use the ideal gas law, PV = nRT, where P is the pressure, V is the volume of the cylinder, n is the number of moles of air, R is the ideal gas constant, and T is the temperature in Kelvin.
The pressure of air in a cylinder is affected by several factors, including the volume of the cylinder, the temperature of the air, the number of moles of air, and the force exerted on the air. Additionally, the type of gas in the cylinder and any external pressure or compression can also impact the overall pressure.
The pressure of air in a cylinder can be measured using a pressure gauge or a manometer. A pressure gauge is a device that measures the force exerted on a unit area of the gauge. A manometer measures the difference in pressure between the air inside the cylinder and the surrounding atmospheric pressure.
Calculating the pressure of air in a cylinder can be useful in a variety of industries, such as in scuba diving to determine the amount of air left in a tank, in manufacturing to ensure proper air pressure in pneumatic systems, and in automotive engineering to optimize fuel efficiency. It can also be used in weather forecasting and in the study of atmospheric pressure.
The pressure of air in a cylinder decreases with increasing altitude. This is because as altitude increases, the air becomes less dense and there is less air above pushing down on the air in the cylinder. This decrease in pressure can also impact the temperature and volume of the air in the cylinder due to changes in the ideal gas law.
