Outside the eye of the storm, the wind field around a hurricane can be modeled as the superposition of a potential sink and an irrotational vortex. If a meteorological observation station 57 km from the center of the storm measures velocity components (i.e. tangential and radial components) of 29ms-1 and 6ms-1. What is the pressure difference at 22 km from the storm compared to that recorded at the meteorological station? Give your answer in Pascals (Pa). The desnity of air is 1.22 kg/m3.
