The cross-section of a fluid bearing is shown below. The concentric cylinders are 10 cm in length. The innercylinder has radius 1.9 cm and is stationary whilst the outer cylinder has radius 2 cm and rotates with an angularvelocity 𝜔 = 500 rad/s. The fluid between the cylinders is S.A.E. 10 oil (density 𝜌 = 917 kg/m3 and dynamicviscosity 𝜇 = 0.104 N.s/m2).𝜔 = 500 rad/s 1.9 cm2 cm10 cmfluid in gap(a) By assuming a linear velocity profile of the fluid in the gap between the two cylinders, estimate the(resistive) torque and the power required to maintain constant angular velocity of the outer cylinder.(b) In arriving at the estimate of part (a) above, what assumptions have been made in the modelling.(c) By estimating the Reynolds number, suggest why the calculations might not be appropriate for the sameparameters except with water (density 𝜌 = 1000 kg/m3 and dynamic viscosity 𝜇 = 0.001 N.s/m2) replacingthe oil.
