Transitional (Reversible) Flow

Transitional (reversible) flow occurs back and forth between two stocks. The Transition Rate rate-controlling variable is connected to the valves in each of the pipes. Each of the flows can vary from zero to a maximum value (practically limited by the capacity of the pipes). Without additional outflows or inflows, which are frequently connected in practice, this is a closed-loop system. Each stock can drain to, or fill from, the other.
