Choose the Best Fluid for Lifting: Hydraulic vs. Pneumatic

[tenpai]

Homework Statement

Right now, I am learning fluids and this question is just asking if i should use either hydraulic or pneumatic fluid for a device that will be able to lift a large fluid.

Homework Equations

For pneumatic systems, flow rate is most often expressed as standard cubic feet per minute (SCFM) or normal liters per minute (nL/min)

The Attempt at a Solution

well i know hydraulic uses oil and pneumatic uses air. I think air is used to lift things up but i think pneumatic is stronger.

What is large fluid? Do you mean just large mass?

Think about compressibility of gases and liquids.
