the difference between system equili and system and steady state
Can anyone explain the difference between a system at equilibrium and a system at steady-state water flow?
I know that equilibrium occurs at equal rates, no net change is produced. But I don't understand steady state system....Please explain it to me.... Thanks also the difference between saturated and unsaturated hydraulic conductivity? I have hard time to understand these stuffs.. If anyone know these stuffs, can u please explain it to me. Thanks. |

I'm moving this to Physics, where perhaps it will get some discussion.

Equilibrium: dU/dx = 0 (usually this happens at extrema of potential energy).

the difference between system equili and system and steady stateSo, that statement of equilibrium would be: [nab].j+∂ρ/∂t=0 ∂A/∂t=0 for any fluid property A. That would include the density ρ, which reduces the continuity equation to: [nab].j=0 edit: fixed ∂ signs. |

I would call steady state a state at which power (rate of chande of energy dU/dt) is constant.
