For each case, calculate an appropriate Reynolds number and indicate whether the flow can be approximated by the creeping flow

Question:

For each case, calculate an appropriate Reynolds number and indicate whether the flow can be approximated by the creeping flow equations. 

(a) A microorganism of diameter 5.0 μm swims in room temperature water at a speed of 0.25 mm/s. 

(b) Engine oil at 140°C flows in the small gap of a lubricated automobile bearing. The gap is 0.0012 mm thick, and the characteristic velocity is 15 m/s. 

(c) A fog droplet of diameter 10 μm falls through 30°C air at a speed of 2.5 mm/s.
