For a reciprocation operation,this plot is modified two ways.
Most of the initial circulation used to reach a steady-state prior to reciprocation is deleted from the plot.Therefore,the time scale should be viewed as incremental time,and not absolute time.
The reciprocation event is cut off from the plot so that only the rise/fall pressure is drawn.in other words,for slow-stroke speeds,the flat constant pressure portions of the curves are extracted from the plots.Therefore,the accelerations and decelerations along with maximums and minimums are presented for consecutive strokes,and the full transient response is cut off to allow the key information to be presented as single plot.
