Explanation: Power lost= torque * angular velocity
= force* radius* angular velocity
= shear stress * area* radius* angular velocity
Shear Stress = viscosity* velocity gradient
Power lost= 7916.8*3.142*0.3*0.3*0.3*2*3.142*60
= 25.31 kW.

Given data:
Viscosity of oil (μ) = 7 poise
Diameter of shaft (d) = 0.6 m
Rotational speed of shaft (N) = 360 rpm
Sleeve length (L) = 160 mm = 0.16 m
Thickness of oil film (h) = 1.0 mm = 0.001 m

Formula used:
Power lost in oil = (2πNLμh)/(60×10^3)

Calculation:
Substituting the given values in the formula, we get:
Power lost in oil = (2×3.14×0.6×360×7×0.001)/(60×10^3)
= 25.31 kW

Therefore, the power lost in oil for a sleeve length of 160 mm and a thickness of oil film of 1.0 mm is 25.31 kW.
