Example: Friction Loss
One litre of water in an adiabatic container is stirred such that the initial average velocity of the water is V1 = 5 m . Stirring stops, and due to internal friction and friction between water and container walls the water will come to rest after a while. The water still moves after the stirrer is removed, but we have no control over the water motion: this is an irreversible process. We compute the change of temperature in the equilibration process.
After stirring stops, the system is isolated, no heat and work are exchanged,
