Examples:

This example shows how to extrapolate a desired feed rate of 3 lbs./hr., based on the feed rates of 3 trial rpm settings.

Observed Feed Rates

Sample 1 = 2 pounds per hour @ 20 rpm

Sample 2 = 4 pounds per hour @ 40 rpm

Sample 3 = 6 pounds per hour @ 60 rpm

In this example, a feed rate of 3 lbs./hr. would be about 30 rpm.
