Question

Flow velocity adopted for design of a grit chamber is

Answer 1

Answer:

Bottom Scour and Flow through Velocity:

A value of 4 is usually adopted for grit particles. For a grit particle size of 0.2 mm, the formula gives critical velocity values of 17.1 to 25.6 cm/s. In actual practice, a horizontal velocity of flow of 15 to 30 cm/s is used at peak flows.
