Information about the seller Adward and his items
The annular gap between the two (D = 210mm; d = 202mm) cylinders is filled with oil (ρ = 910kg / m3) at a temperature of 200C. The outer cylinder rotates evenly at a speed of 120 rpm. Determine the dynamic and kinematic viscosity of the oil if the moment applied to the outer cylinder is T = 0.065 * Z (N * m), and the height of the liquid column in the gap between the cylinders is h = 120 mm. The friction of the base of the cylinder on the liquid is neglected.
