Homework Help: If given a device to lift a large mass, would you use a hydraulic/pneumatic fluid?

  1. Feb 23, 2009 #1
    1. The problem statement, all variables and given/known data
    Right now, im 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.


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


    3. 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.
