    Customer leak spec:
    External Air pressure of .45 kg/cm2 (6.4 psi), less than 4.5x10-2 cc/sec leakage to the inside of the device.


    I need to quantify the amount of bubbles per minute would the leak spec above allow for?
    (given that a bubble under water is about 30 - 50 mm3).


    (also we leak test in hot water so the opposite of spec).

    can someone help provide a solution to this.

    Thanks.

    Bonll:

    0.045 cc/sec (45 mm^3/sec) means that you should expect to get on the order of 60 bubbles per minute.
