Edit

: I am an Engineering student, finishing studies.: I am designing a extruder for paste. I am looking for a formula for work, because I have to decide a motor.: My screw is similar to a Archimedes screw.: thankz, and excuse my poor EnglishThe motor may be sized on 2 factors: the first is the volume of paste per unit time. The second is the working pressure. Multiplying the two gives the power required to drive the screw. Then the volume/revolution of the screw can be divided into the volume per unit time to give the motor RPM.
