Homework Statement Hi guys, I'm pretty new here, and long story short, I'm struggling a bit on a fluid mechanics question I've been doing for some revision. A shaft 70 mm in diameter is being pushed at a speed of 400 mm/s through a bearing sleeve 70.2 mm in diameter and 250 mm long...

Well to be honest, I'm not sure whether this is correct or not, but this is what I have so far. I have found µ (the dynamic viscosity coefficient) to come up to be 4.5kg/(ms). Then I went on to find τ (Shear Stress) to be 7.2 And this is basically where I get stuck. Once again, I have no...
