L/D - typically, barrels are built-up by independently thermoregulated modules having 4-diameter length each;
Output - the ranges here above want to give an idea on limits considering a variety of cases, but, figures can only be very indicative; actually achievable values strongly depend on raw material formulations, target products and relevant desired characteristics, as well as speed and process conditions.
