AI Thread Summary
Increasing the speed of fluid flow does not directly increase its temperature. Fluid temperature is determined by the average kinetic energy of individual molecules, not by the speed at which the fluid is moving as a whole. Forcing water out of a faucet faster does not raise its temperature, as the thermal motion of the molecules remains unchanged. The collective motion of the fluid does not influence the thermal energy of its molecules. Therefore, faster flowing water does not equate to a higher temperature.

Hi, I have a question about fluid temperature.

I have a vague understanding that a fluid's temperature is its average kinetic energy. So, a hotter fluid has faster moving molecules on average.

What I'm wondering is, if you force water out of a faucet harder to make the water come out faster, does this increase its temperature? If the water falls out faster, does that mean it has a higher kinetic energy, and therefore temperature, than if it came out slower?

Thanks!

The fluid temperature is related to the magnitude of the thermal motion of the molecules in the fluid, not the collective motion of the fluid as a whole.

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...
