In cylindrical coordinates the momentum flux is given by (in the r direction): Π = − η ∂ ( r ω) ∂ r. Where η is the viscosity. Therefore one would expect that the shear stress in the θ direction would be given by: τ = η ∂ ( r ω) ∂ r. I have, however, seen is said that in this case the sear stress is ...
