7.3.2.1 Plunger area/diameter variation

Figure: pressure at the plunger tip, , the flow rate, , and the gate velocity, as a function of plunger diameter ,

First, the effect of plunger diameter size variation is examined. In section [*] it was shown that . Equation ([*]) demonstrates that increases with an increase of 8.

Figure: as a function of

The value can attained is an infinite value (according to the ``common'' model) therefore is infinite as well. The gate velocity, , increases as the plunger diameter decreases as shown in Figure [*]. Armed with this knowledge now, several cases can be examined if the trends are realistic.
