How do you determine the pressure within an unopened can of cola between the soft drink and the can?

Question

what formula or procedure do you follow in determining the pressure inside of an unopened cola can between the soft drink and the can?

Answer 1

Several ways.  Remember it will vary with temperature, and age of can and with variations in manufacturing process, and from type to type of cola. And by how much you shake it!

1) open the can inside a larger sealed container. Measure the pressure increase in the larger container, and it's volume and calculate back the the pressure inside the can.

2) design a probe that you can use to punch thru the can, making a small opening that is sealed by the probe. Attach a pressure meter to it.

3) you may be able to get somewhere by pushing against the semi-flexible can and measuring the counter pressure.  this would need a lot of experimentation tho.
