How much suction required to lift?

So in summary, suction can have varying effects on different objects and can potentially worsen the situation when choking.

Hi - am looking for some data points on how much suction is required to lift an object at different weights and volumes.

Especially interested in any data relative to displacing an object caught in the throat if you are choking.

Appreciate any help!

Well the problem with suction in this sense is that it acts in all directions unilaterally. i.e.
rather than pull an object out, it will have more of a tendency to collapse the throat, making the problem worse.

If you use a drinking straw to drink a milkshake, you're OK as long as the shake isn't too thick, and the straw is rigid. But if you flatten the straw, decreasing its rigidity, it will simply collapse every time you suck on it.
 

1. What is suction and how does it work?

Suction is the force created by a difference in air pressure that allows objects to stick or be lifted. It works by creating a lower air pressure on one side of an object than the other, causing the object to be pushed towards the area of lower pressure.

2. How is suction measured?

Suction is typically measured in units of pressure, such as pounds per square inch (psi) or pascals (Pa). However, the specific measurement will depend on the tool or device being used to create suction.

3. What factors affect the amount of suction required to lift an object?

The amount of suction required to lift an object depends on several factors, including the weight and surface area of the object, as well as the strength of the suction device and the surrounding air pressure.

4. Can suction be used to lift any type of object?

In theory, suction can be used to lift any type of object as long as there is a difference in air pressure and the object has a surface area that can create a seal with the suction device. However, the amount of suction required may vary greatly depending on the object's weight and other factors.

5. How can I calculate the amount of suction required to lift a specific object?

The amount of suction required to lift an object can be calculated by considering the weight of the object, the surface area in contact with the suction device, and the surrounding air pressure. There are also online calculators and formulas available that can assist in determining the necessary amount of suction.
