Litre per Second (L/s)
Litres per second express small discharges: tube-well yields, drains, field channels and water-supply mains.
Symbol: L/s
Quantity: volumetric discharge of rivers, canals and water supply
SI relation: 1 L/s = 0.001 m³/s (exact)
Derivation: 1 L/s = 10⁻³ m³/s.
Exact: yes, by definition
Typical uses
- Tube-well and pump discharge
- Drainage coefficient and field drains
- Water-supply design
