It is remarkable that there were so few contributions made in the area of a filling or evacuation gaseous chamber. The earlier work dealing with this issue was by Giffen, 1940, and was republished by Owczarek, J. A., the model and solution to the nozzle attached to chamber issue in his book ``Fundamentals of Gas Dynamics.''1.46. He also extended the model to include the unchoked case. Later several researchers mostly from the University in Illinois extended this work to isothermal nozzle (choked and unchoked).
The simplest model of nozzle, is not sufficient in many cases and a connection by a tube (rather just nozzle or orifice) is more appropriated. Since World War II considerable works have been carried out in this area but with very little progress1.47. In 1993 the first reasonable models for forced volume were published by the undersigned. Later, that model was extended by several research groups, The analytical solution for forced volume and the ``balloon'' problem (airbag's problem) model were published first in this book (version 0.35) in 2005. The classification of filling or evacuating the chamber as external control and internal control (mostly by pressure) was described in version 0.3 of this book by this author.
