Does a Tube's Length Affect Force at the Same PSI?

[alfiez23]

Does a 12" x 1.5"D tube filled with 10psi have more force on an piston than a 6" x 1.5"D tube filled with 10psi?

Or is 10psi the same on an object no matter what size the tank...

What is the area this pressure is acting on? Is it the same or different between the two cases?

 

[alfiez23]

The area of the piston would be the same.

Lets say you have a conventional bicycle tyre pump (eg piston in a tube). The force you need to apply to the pump handle depends on the pressure in the tyre and area of the piston and NOT the volume of the tyre.

I would say that the answer to this question depends on the context and specific variables involved. In general, pressure (psi) is a measure of force per unit area, so in this scenario, a 12" x 1.5"D tube would have a larger surface area and therefore potentially exert more force on a piston compared to a 6" x 1.5"D tube. However, there are other factors at play such as the material and design of the tubes, the size and shape of the piston, and the surrounding environment. Additionally, the concept of force also takes into account the direction and magnitude of the applied pressure. Therefore, it is not accurate to say that 10psi will have exactly the same force on an object no matter what size the tank is. Further analysis and experimentation would be necessary to determine the specific force exerted in each scenario.
