Calculating Air Pressure for 10-Meter Liftoff with Air Pump

In summary, the person needs to lift 120kg of weight, including equipment, 10m off the ground in 10 seconds. The propulsion will be pressurized air from a conventional air pump with a pressure output of 2 nozzles with a diameter of 100mm each. The questions to be answered are: A) How many Bar air pressure of the air pump is required? B) How many cubic meters of air will be the output of the air pump? Based on calculations, the air pump will need to output 928m3 of air to achieve the lift, and the required air pressure would be 120 Bar.

Hi guys,
i need your help, in finding the right equation.

1.) I want to lift up a person including equipment 10m of the soild ground in 10 seconds.
2.) The persons weight (including equipment) is 120Kg
3.) The propoulsion will be press'd air (NOT hot turbine air), just by a conventional air pump.
4.) The presure output, will be 2 nossles, wit a diameter of 100mm each.

Now the question is:
A.) How many Bar air pressure of the air pump is required?
B.) How many cubic meter of air will be the output of the air pump

now my thought have been:

120Kg * 10m = 1200Kgm
= 120kg/1.293(1kg of air) = 92.80m3/s
= 92.80m3/s * 10m (high) = 928m3

1.) airpump air volume needed = 928m3?
2.) 120kg = (kg=L=Bar) = 120 Bar??
 

1. What is air pressure liftoff force?

Air pressure liftoff force is the upward force that is generated when a gas, such as air, is compressed under a surface. It is a result of the pressure difference between the top and bottom of the surface and is responsible for lifting objects, such as airplanes or rockets, off the ground.

2. How does air pressure liftoff force work?

Air pressure liftoff force works by creating a difference in pressure between the top and bottom of a surface. This pressure difference creates an upward force, which is greater than the force of gravity, allowing an object to lift off the ground.

3. What factors affect air pressure liftoff force?

There are several factors that can affect air pressure liftoff force, including the shape and size of the surface, the speed at which the surface moves through the air, and the density and temperature of the air. These factors can impact the amount of air pressure that is generated and, therefore, the amount of lift that is produced.

4. How is air pressure liftoff force calculated?

Air pressure liftoff force is calculated using the Bernoulli's principle, which states that as the speed of a fluid (such as air) increases, its pressure decreases. This principle can be applied to calculate the amount of lift produced by a surface, taking into account factors such as the speed of the surface, the density of the air, and the shape and size of the surface.

5. What are some real-world applications of air pressure liftoff force?

Air pressure liftoff force has many real-world applications, such as in the design of airplanes, helicopters, and rockets. It is also used in the creation of lift-generating devices, such as wings and airfoils, which are used in various industries, including transportation and wind power. Understanding and harnessing air pressure liftoff force has been crucial in the development of modern air and space travel.
