Part 2: Velocity Measurements<br />

◦ Re-Calibrate the velocity of the water tunnel as a function<br />

of impeller motor rpm for use in subsequent<br />

hydrodynamic experiments using Laser Doppler velocity<br />

measurements<br />

◦ Make measurements of the drag coefficient of a circular<br />

cylinder at three (0.8, 1.4 & 1.8 m/s) different flow<br />

velocities. Both velocity calibration and drag<br />

measurements are based on velocity measurements<br />

from a laser-Doppler Velocimeter.
