Fluid flow with fluid pressure p(t, {\bf r}) and velocity {\bf u}(t, {\bf r}) are not changing in time:
| p(t, {\bf r}) = p({\bf r}) |
| {\bf u}(t, {\bf r}) = {\bf u}({\bf r}) |
The fluid temperature T(t, {\bf r}) is supposed to vary slowly enough to provide quasistatic equilibrium.
This flow regime is often observed in pipeline fluid flow and reservoir fluid flows
