Question

EXAMPLE 5-9 The Rise of the 0cean Due to a Hurricane A hurricane is a tropical storm formed over the ocean by low atmcspheric 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. Hurricane Figure 5-43 depicts a hurricane hovering over the ocean swell below. The atmospheric pressure 200 mi from the eye is 30.0 in Hg (at point ї, gener- ally normal for the ocean) and the winds are calm. The atmospheric pressure at the eye of the storm is 22.0 in Hg. Estimate the ocean swell at (a) the evel 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/ft and 848 lbm/ft3, respectively, and the density of air at normal sea-level tempera- ture and pressure to be 0.076 Ibm/ft3 Calm ocean Ocean

Please give a step by step change in equation to solve for h3 for (a) and show step by step how to get pressure and density for (b).
