For a conical bearing, 100 watt power gets dissipated when a shaft with maximum cone radius 10 cm turns with 600 rpm over a uniform fluid layer of thickness 0.1 cm. If semi-angle for the conical bearing is 30°, make calculations for the dynamic viscosity of the fluid (in SI units).
Correct answer is 'Range: 0.08 to 0.09'. Can you explain this answer?

Consider an elementary ring of bearing surface of radius r and thickness dh at a distance h from the cone apex. Then r = h tan α and bearing area of the elementary ring equals dA = 2πr (dh sec α)
= 2πh tan α dh sec α
Viscous shear stress,
Since the shaft has an angular velocity ω, The tangential velocity, u = ωr = ωh tan α
∴ Viscous shear stress,
Tangential resistance on the ring, dF = shear stress × area of the ring
Torque = moment of tangential resistance = dF × r = dF × h tan α
