I have temperature readings from thermocouple at the midpoint of a screw conveyor moving dried solids from a rotary dryer. How can I use the available temperature data to calculate the temperature of the material entering the screw conveyor?
Without some idea of the heat loss through the first half of the conveyor, I don't think you really can. You could put a temporary thermocouple at the beginning of the conveyor and attempt to derive a relationship that includes SlideRuleEra's points, but at that point you might as well make it a permanent thermocouple.
