Unravelling the Mystery of Wind Damage and Kinetic Energy

AI Thread Summary
The energy associated with wind damage from a hurricane is derived from the relationship that energy increases with the cube of wind velocity, which contrasts with the kinetic energy formula that relates energy to the square of velocity. This cubic relationship accounts for both the kinetic energy of the moving air and the pressure exerted by the wind. The pressure component, which is linear with energy, contributes to the overall impact of wind speed on damage potential. Understanding this relationship is crucial for accurately assessing hurricane damage. The discussion highlights the complexity of wind energy dynamics beyond simple kinetic energy calculations.

Hi Guys,

I understand that the energy associated with wind damage from a hurricane goes as the third power of the velocity of the wind.

How is this relationship derived? I ask because when I think of wind energy, I think of Kinetic Energy going as the square of the velocity. Intuitively, this third power does not seem correct!

Thank you,
Bob

Energy in moving air comes from both velocity and pressure. The pressure component is linear with energy.

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...

Thread 'Recovering Hamilton's Equations from Poisson brackets'

The issue : Let me start by copying and pasting the relevant passage from the text, thanks to modern day methods of computing. The trouble is, in equation (4.79), it completely ignores the partial derivative of ##q_i## with respect to time, i.e. it puts ##\partial q_i/\partial t=0##. But ##q_i## is a dynamical variable of ##t##, or ##q_i(t)##. In the derivation of Hamilton's equations from the Hamiltonian, viz. ##H = p_i \dot q_i-L##, nowhere did we assume that ##\partial q_i/\partial...
