This model is highly dependent on the transfer ef
ciency of the system. As the DMA
increases, so does the TMA, but not in
nitely. Figure 10.23b shows the relationship
between the transferred mass and the developed mass. Note that the dotted line
represents 100% transfer ef
ciency, which is impossible for a practical system to
achieve. The TMA increases proportional to the DMA and linearly for most of the
