Abstract
A procedure is proposed in the paper whereby the quantity of air forced into a pressed blank can be calculated. The calculations are done in the general form and with reference to a specific example, using the compaction pressure, compaction ratio, gas content, and gas permeability of the pressed work. Graphs are constructed which relate the variables of compaction and adiabatic discharge of air from the pressed work to the compaction pressure and the duration of the pressing operation.
