The wind velocity at a location 5 km away from the centre of a tornado (consider inviscid, irrotational vortex motion shown in Fig 7.7) was measured as 30 km/hr and the barometric pressure was 750 mm of Hg. Calculate the wind velocity 1 km from the tornado centre and its barometric pressure. (Density of air = 1.2 kg/m³
, density of mercury = 13.6 × 10³
kg/m³).
