Answer 2

Answer:

The answer is 15 cm/min to 30 cm/min.

Explanation:

• Flow velocity in any sedimentation tank should not exceed 15 cm/min to 30 cm/min.
• The velocity of flow of water in sedimentation tanks should be sufficient enough to cause hydraulic subsidence of suspended impurities. It should remain uniform throughout the tank and it is generally not allowed to exceed 15 cm/min to 30 cm/min.
