An incompressible Newtonian fluid, filled in an annular gap between two concentric cylinders of radii R1 and R2 as shown in the figure, is flowing under steady state conditions. The outer cylinder is rotating with an angular velocity of Ω while the inner cylinder is stationary. Given that (R2-R1)«R1 the profile of the θ-component of the velocity Vθ can be approximated by,
A
R2Ω
B
(r-R2)/(R2-R1)rΩ
C
(r+R1)/(R2+R1)R1Ω
D
(r-R1)/(R2-R1)R2Ω

Correct : d
