Terminal velocity in the presence of buoyancy force Settling velocity W s of a sand grain (diameter d, density 2650 kg/m 3) in water at 20 Â°C, computed with the formula of Soulsby (1997). When the buoyancy effects are taken into account, an object falling through a fluid under its own weight can reach a terminal velocity (settling velocity) if the net force acting on the object becomes zero.
