Estimate the ocean swell at (a) the eye of the hurricane at point 3 and (b) point 2,
A hurricane is a tropical storm formed over the ocean by low atmospheric pressures. As a hurricane approaches land , inordinate ocean swells (very high tides) accompany the hurricane. A Class-5 hurricane features winds in excess of 155 mph, although the wind velocity at the center “eye” is very low. depicts a hurricane hovering over the ocean swell below. The atmospheric pressure 200 mi from the eye is 30.0 in Hg (at point 1, generally normal for the ocean) and the winds are calm. The atmo spheric pressure at the eye of the storm is 22.0 in Hg. Estimate the ocean swell at (a) the eye of the hurricane at point 3 and (b) point 2, where the wind velocity is 155 mph. Take the density of seawater and mercury to be 64 lbm/ft3 and 848 lbm/ft3, respectively, and the density of air at normal sea-level temperature and pressure to be 0.076 lbm/ft3.
