Dear all,

Suppose I got a 1 m^3 cube with one pumping port. Is that possible I can simulate

the pressure of the cube related to pumping time?

Any comments are very welcome.

David

Hi

If you kknow the pump characteristics w.r.t. pumping folow depending on the pressure difference etc, I believe so.

You should write down what you have s variable and what you need to know

Good luck
