Calculate the terminal settling velocity for sand in water at 10C having particle diameters of 75 and 180 m and a density of 2650 kg/m

Calculate the terminal settling velocity for sand in water at 10◦C having particle diameters of 75 and 180 μm and a density of 2650 kg/m³. The density and viscosity of water at 10◦C. Also use the Reynold’s number to classify the flow type. μ = 1.307 N · s/m2 (or kg/m · s) and ρw = 999.7 kg/m³.
