What torque is required to drive the disk

Reference no: EM13529927

A 2.25 Adisk spins within an oil-filled enclosure,having 2.4-mm clearance from flatsurfaces each side of the disk. The disk surface extends from radius 12 to 86 mm.What torque is required to drive the disk at 660 rpm if the oil's absoluteviscosity is 0.12 N.s/m2?
