This chapter is the second on the section dealing with filling
and evacuating chambers.
Here the model deals with the case where the volume is controlled
by external forces.
This kind of model is applicable to many manufacturing processes
such as die casting, extraction etc.
In general the process of the displacing the gas (in many cases air)
with a liquid is a very common process.
For example, in die casting process
liquid metal is injected to a cavity
and after the cooling/solidification period a part is obtained
in near the final shape.
One can also view the exhaust systems of internal combustion
engine in the same manner.
In these processes, sometime is vital to obtain a proper evacuation
of the gas (air) from the cavity.
