In a rolling operation, a plate of 2 cm thick and 25 cm wide is passed through a rolling millhaving 2 powered rolls. Assume friction was enough for rolling. Thickness of the plate atthe end of operation is 1.7 cm. Each roll has a radius of 0.3 m and a roll speed of 0.5revolution per second. Flow curve has the following values K = 225 MPa and n = 0.15.

Determine the power required for driving the rolls.
