Force required to compress air

  1. Feb 26, 2017 #1
    I have a tube 40' long by 8" internal diameter, sealed at one end.

    Assuming an ideal plunger is inserted into the open end, how much force would be required to compress the air (starting at 1 atm) from 40' (1005 ft/cu) to 36' (904 ft/cu)?

    Any hints as to the calculation required for this would be appreciated.
    Thank you.

    Are you familiar with the ideal gas law?
