(II) Estimate the air pressure inside a category 5 hurricane, where the wind speed is 300 km/h (Fig. 10-52).
Hurricane is formed due to pressure difference. We have to find out the air pressure inside a category 5 hurricane where the wind speed is .
Step 1 of 2</p>
According to Bernoulli principle for the air moving at same height, the sum of the pressure energy and kinetic energy of the air always remains constant.
Pressure at any point in the system
Velocity of air at the same point
Density of air
Step 2 of 2</p>
As we know that the pressure outside hurricane is the atmospheric, therefore,
As the air molecule start moving from outside the hurricane to inside, therefore speed of wind outside the hurricane is zero.
As the air molecule start moving from outside the hurricane to inside, its speed increases, therefore speed of wind inside the hurricane is,
