3. You are trying to remove 10.0 mm diameter particles in a water treatment plant. The water is at 15°C, and the particle density is 1.35 g/ml. The plant treats 0.100 m³/s of water. It is proposed to use a 3 m deep, rectangular sedimentation tank with a length to width ratio of 6:1.
a. What is the minimum required width of the basin?
b. What would be the minimum required width if the water in this problem was 25°C, instead of 15°C?
