5.4 Sediment Handling measures: Methods of bed load and suspended load handling in RoR headworks, Design of settling basin (Particle and concentration approach), Estimation of sediment volume in Settling basin, Flushing of deposited sediment, estimation of frequency of flushing
Design a settling basin for particle size = 6 mm, sp. gravity = 2.65, absolute viscosity = 1.34 gm/cm-s, temperature of water = 20°C, discharge = 12 m³/s. Calculate depth of sediment assuming concentration is 5000 ppm. Assume 15% flushing discharge and performance coefficient of Hazen = 0.16. Draw neat sketch of plan and section. [8+2]
