About equilibrium pressure:

When two reservoirs containing a gas are connected, the pressure equalizes between them. This calculation is based on the principle of conservation of mass and the ideal gas law, where the product of pressure and volume remains constant at constant temperature.

This simulation is particularly useful for estimating the final pressure during the transfer of refrigerants or gases between cylinders, or during system commissioning.
