Bulk Modulus of a liquid

[Dougt115]

If I vacuum a liquid down to 1 micron and then return it to atmospheric pressure will the bulk modulus change? I expect it will increase, become harder to compress.

I don't think that your fluid's bulk mod will change much (practically speaking) with a 15psi change in pressure. However if a phase change over that pressure range is possible, which it just might be, there will be dramatic bulk mod changes.
Generally these are more sensitive to temperature.

you must get smarter than the software you're using.
