We begin by considering the steady-state conditions: and.
The meteorology of a whole world, even under steady-state conditions, was a matter of enormous complexity.
Under steady-state conditions it would be typical for the force to vary up and down from this value.
During steady-state conditions, the flow, pressures, etc. in the pipeline are (more or less) constant over time.
It is only useful in steady-state conditions, however, and its ability to deal with gas pipelines is limited.
Note - the above equation (11) is valid only for the steady-state condition.
As before, frictionless flow in steady-state conditions implies that .
At steady-state conditions, the vapor and liquid on each tray reach an equilibrium.
He also agreed that sustainability could not be conceived of as some permanent, steady-state condition.
The smaller the system, the shorter the residence time will be, again assuming steady-state conditions.
