Use consistent units and the requested inputs.
Use the main result and breakdowns as a planning estimate.
For regulated topics, verify current local rules before acting.
Idealized constant-outlet emptying time (h) = V(m³)/Qout(m³/s)/3600. This ignores a head-dependent outlet flow.
Worked example: V=1000 m³, Qout=0.2 m³/s; result = 1.3888888889 h.
Physical meaning: Idealized constant-outlet emptying time (h) = V(m³)/Qout(m³/s)/3600. This ignores a head-dependent outlet flow.
These simple mass-balance estimates assume nonnegative CONSTANT inlet/outlet discharge. Emptying time also assumes a constant outlet even if real outlets respond to head. They do not calculate a storm hydrograph, detention routing, emergency spillway capacity, or regulatory required storage volume.
