If a different piece of the cold rolled sheet of part (a) is 0.54 m wide and rolled at 6200 cm/min on work rolls of 535 mm diameter, estimate the rolling mill power required for the thickness reduction from 1.1 mm to 0.79 mm. Assume mineral oil is used as a lubricant, giving a friction coefficient of 0.1.
