How to calculate tank pressure equalization

I have a question: Two storage tanks (air, A at 5MPA and B at 1MPA) are connected to equalize the pressure. How should the pressure in the tanks be calculated after equalization? Is the final pressure of the two storage tanks related to their volumes? Once the isolation valve between the two storage tanks is opened, how is the pipe flow rate calculated?

Yes, according to the constant amount of substance, pv=nrt

I don’t know how to calculate the flow rate either; it is recommended to use Bernoulli’s equation to obtain an approximate value, and then estimate a range of variation
