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. The clearance, assumed uniform, is filled with oil
with kinematic viscosity ν = 0.005 m^2/s and density ρ = 900 kg/m^3. Find the force exerted by the oil on the shaft. (ans.: 990 N)
As you see, I have the answer given to me, but I do not quite get the working out. Can somebody please help me out? :(
Thanks in advance
