AI Thread Summary
To estimate the air pressure at the center of a category 5 hurricane with a wind speed of 328 km/hr, one should apply Bernoulli's theorem to relate the pressure difference between normal atmospheric pressure and the hurricane's center. The discussion emphasizes the importance of doing the calculations independently, while also encouraging guidance on initial steps. It is crucial to ensure that seeking help complies with academic integrity policies. The user expresses uncertainty about how to start the problem but is willing to proceed once given some direction. Understanding these principles is essential for accurately calculating the pressure in such extreme weather conditions.

Pleaseeeeeeeeeee i need this!exammmmm

Estimate the air pressure at the centre of a category 5 hurricane with a wind speed of 328km/hr.
Hint: start with the pressure difference btw normal atmospheric pressure at a long distance away from the hurricane and the pressure at the centre and use Bernoullis theorem to relate this to the wind speed difference..
Give the answer in kPa or kilo-Pascals where 1 kPa = 1000Pa.

That's not the way it works here, we'll help you, but you have to do the work yourself.

Note: If this is part of a take home assessment, please ensure that both your school/college and course instructor permit you to receive external assistance.
 


reason i put this up here is because i don't even know where 2 begin. if you show me the first step or twoo then I am fine with that.

thank u

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
