Abstract
Results are shown of measurements which have been made for the purpose of determining the work of external forces required to fill a rectangular channel with polymer melt under constant pressure or periodically variable pressure (at a frequency of 6–17 Hz). It has been established that filling a channel under pulsating pressure requires 1.5–1.7 times less energy than filling it under steady flow conditions.
