Dear guys,
As you see in picture, there is a two rolls.

Top roll have a Rubber Surface Coating (Weight : 1000kg, OD:550mm, ID: 448mm, Face Length : 1950mm),
Bottom roll (Weight : 1500 kg, OD:605mm, ID: 535mm , Face Length : 1950mm ) is a steel surface.

Now the paper pass between them, and load applied to press the paper, (Nip Pressure) is 200 kg/m².

And my question is, How can I calculate HP required to rotate the roll at 100 rpm.

NOTE: i even make the formula table (Attached Herewith) from the another post given in the http://www.physicsforums.com/showthread.php?t=201254, But the load consideration is not there..

Please Help Me to find HP of motor and Appropriate gear box.....

Regards, Rishit Mevada
