Step 1
We can use the Reynolds number to do this: Re = (Ļvd)/Ī¼ where Ļ is the density of water, v is the velocity over the sphere, d is the diameter of the sphere, and Ī¼ is the viscosity of water. Plugging in the values given, we get: Re = (1000 kg/m3)(3 m/s)(0.01 Show moreā¦

A 13-mm-diameter plastic sphere whose density is 1150 kg/mĀ³ is dropped into water at 20Ā°C. Determine the terminal velocity of the sphere in water. The density and dynamic viscosity of water at 20Ā°C are Ļ = 998 kg/mĀ³ and Ī¼ = 1.002Ć10ā»Ā³ kg/mĀ·s, respectively. The drag coefficient for a sphere in laminar flow is CD = 0.5. The terminal velocity of the sphere in water is m/s.
