A hurricane with a radius of 200kmand a maximum wind speed of75km/hr is to be modeled by a bathtub vortex with a radius of 0.3mand maximum velocity of 0.2m/s. Assuming that the flow is accurately described by the free-vortex model in both cases, compute the ratio of the Coriol is force to the centrifugal force at a latitude of 45◦.
