the work metal has a flow curve defined by K=300MPa and n=0.2, and the coefficient of friction between the rolls and the work is assumed to be 0.1. a 250mm wide strip 2.0cm thick is fed through a rolling mill with two powered rolls each of radius=300mm. the work thickness is to be reduced to 18mm in one pass at a roll speed of 50rev/min. what will be the power for this operation?
