Question

A ship is towing a sonar array that approximates a submerged
cylinder 1 ft in diameter and 30 ft long with its
axis normal to the direction of tow. If the tow speed is
12 kn (1 kn = 1.69 ft/s), estimate the horsepower required
to tow this cylinder. What will be the frequency of vortices
shed from the cylinder? Use Figs.
