Question

The mean sustained wind velocity, v, can be determined by the equation , where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?

103 millibars
194 millibars
363 millibars
910 millibars

Answer 1

The mean sustained wind velocity has the equation:

v = 6.3 √(1013 - p)

If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:

64 = 6.3 √(1013 - p)

64/6.3 = √(1013 - p)

10.1587² = 1013 - p

p = 910 millibars

hope this helps!!!!!!!!!!!!
