Calculating differential pressure across a seal

  1. Apr 25, 2007 #1
    Hey I need help trying to calculate the differntial pressure across a seal.
    I know the tensile strength of the material used for sealing and the difference in the 2 diameters of the 2 cylinders that need sealing. Only problem is the distance is 0.3m and my seal is 3m long (the whole thing can therefore extend and contract up to 3 m) and so it will be hanging down in a "u shape".

    I was thinking I would just use F=dp*A but I'm not sure which area to use (i.e. the cross sectional area of the "donut" area of the actual length of the seal?)
