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.
Circular diameter d=1000 sqrt(4Q/[pi Cd sqrt(2gH)]) in millimetres.
Inputs: Q=0.02 m³/s, Cd=0.62, H=3 m (evaluate using the calculator above).
Circular diameter d=1000 sqrt(4Q/[pi Cd sqrt(2gH)]) in millimetres.
Incompressible quasi-steady free discharge; effective head is measured to orifice centreline for free flow or differential head for submerged flow. Coefficient Cd depends on edge/approach/submergence and must be calibrated. An ideal speed formula does not predict actual exit flow without contraction/losses.
