It's rotating at rate Ω .During this question we get that the motion of a uniform axisymetric flow is: ∂ u θ ∂ t = ν ( ∂ 2 u θ ∂ r 2 + 1 r ∂ u θ ∂ r − u θ r 2) We are told that the specific axial angular momentum is given by: m = r u θ Solving for steady state I then find that: u θ = Ω a 2 r WebThe fluid temperature is raised as the thermal radiation parameter rises in the situation of laminar flow in horizontal concentric cylinders with uniform heat flux. This is because a higher thermal radiation parameter translates into a stronger radiative heat transfer, which accelerated the fluid's heating. canadian public service letter of offer
