3. A bird with a body length of 10 cm is flying at 10 m/s through air (viscosity of 18.27 x 10-6 Pas, density of 1.225 kg/m³). a. What is the bird's Reynolds Number (Re)? b. Will there be vortices associated with the flow around the bird? Assume similar transition Re as described in class. c. The bird dives into the water, keeping the same speed. What is the new Re? Water has a viscosity of 1.31 * 10-³ Pas and a density of 1000 kg/m³. d. Will there be vortices associated with the flow around the bird? Assume similar transition Re as described in class.

Question
Transcribed Image Text:3. A bird with a body length of 10 cm is flying at 10 m/s through air (viscosity of
18.27 x 10-6 Pas, density of 1.225 kg/m³).
a. What is the bird's Reynolds Number (Re)?
b. Will there be vortices associated with the flow around the bird? Assume
similar transition Re as described in class.
c. The bird dives into the water, keeping the same speed. What is the new
Re? Water has a viscosity of 1.31 * 10-³ Pa · s and a density of 1000 kg/m³.
d. Will there be vortices associated with the flow around the bird? Assume
similar transition Re as described in class.
