Flow rate table pipe filling 95%
The calculation has been made by the GAUCKLER – STRICKER method.
The roughness parameter suggested by ASTM for standard ducts with manholes, adapters, bends and gully pots: Ks = 80.
The suggested velocities are:
- 0.5 to 4 m/s for black waters
- 0.5 to 7 m/s for rainwater.
