Output Variation 1
Vol. 17 #2, July 1990

Flow variation can be estimated by measuring the pressure variations using the following equation:

dQ (%) = (d P (%)/n)

where n is the power law index of the resin being extruded. Understanding this equation helps one to realize the importance of main taining a uniform head pressure, if constant flow rate is important.

Note: This formula has been corrected from the misprint that occurred in the original newsletter.
