A strip of 1120mm width and 8mm8mm thickness is rolled between two 300 mm-diameter rolls to get a strip of 120mm width and 7.2mm thickness. The speed of the strip at the exit is 30m/min. There is no front or back tension. Assuming uniform roll pressure of 200MPa in the roll bite and 100% mechanical efficiency. Calculate the minimum total power (in kW) required to drive the two rolls.
