    a jet is kept at 70% of atmospheric pressure. at an altitude of 10000m pressure is 1/3 normal atmospheric pressure. what force must be resisted by seals of a passenger door dimensions 1m by 2m.
    atmospheric pressure corresponds with 1.0 * 10^5Nm^-2

    Force = Pressure x Area

    or conversely Pressure = Force / area
