What torque is required to drive the disk at 760 rpm

Reference no: EM13544531

A flat disk spins within an oil-filled enclosure. Clearances between the enclosure to both sides of the disk is 2.3 mm. The disk surface (area subject to shear) extends from radius 10mm to 90 mm. What torque is required to drive the disk at 760 rpm (rpm is revolution per minute) if the oil’s absolute viscosity is 0.12 N s/m2?
