Concept and Importance of Reynold's Number, and Practice Calculating It. Concept of Pressures, both static and dynamic pressure.

Table I contains data for a larval tunicate and a shortfin Mako shark swimming in sea water at 15°C. Use these data in the following problems:

Tunicate shark cruise shark burst
Animals length 2 mm 4 meters 4 meters
Swim speed 10 mm s-1 70 km hr-1 144 km hr-1
dynamic viscosity 15°C 1.1375 mPa s
kinematic viscosity 15°C 1.1386 mm2 sec-1
density sea water 15 °C 1.025kg L-1

A. (1pt) Calculate the Reynolds numbers for the tunicate, the shark while cruising, and the shark during burst swimming. Show your work. Will inertial or viscous forces dominate the swimming behavior in each case?

B. (1pt) Is the flow likely to be laminar or turbulent in each situation?
