A 1800 ft³ sedimentation tank with a water depth of 12 feet is used to remove sand particles from water by settling. The specific gravity of the sand particles is 2.65 and the diameter of the particles is 0.001 cm. The temperature of the water is 60°F (15.6 °C). Adjust both the kinematic viscosity and the density of water accordingly. a. Calculate the settling velocity (m/hr). b. Assuming this settling velocity is the overflow rate, calculate the hydraulic residence time (hr)
