## terminal velocity

1. the constant maximum velocity reached by a body falling under gravity through a fluid, esp the atmosphere
2. the maximum velocity that an aircraft can attain, as determined by its total drag

## terminal velocity

[′tər·mən·əl və′läs·əd·ē]
(fluid mechanics)
The velocity with which a body moves relative to a fluid when the resultant force acting on it (due to friction, gravity, and so forth) is zero.
(physics)
The maximum velocity attainable, especially by a freely falling body, under given conditions. Also known as terminal speed.

## terminal velocity

In an air-conditioning system, the average velocity of an airstream at the end of its throw; one of the indicators of drafty conditions and comfort level.

## terminal velocity

The maximum speed a freely falling object can reach when falling through the air. In an aircraft, it is the maximum velocity at which the drag has reached an amount in which the aircraft will not continue to accelerate downward.

Therefore by comparisons of terminal velocity as a function of particle sizes between the work of [17] and the present work, it is found from Figure 12 that [17] started by a finest particle equal to 0.5 [micro]m in diameter; however the finest particle used in this work is clay 1.46 [micro]m in diameter which settles so slowly; it falls at 1 mm/s, concerning the other particles (small silt, large silt, and sand); the settling velocity values reveal a good correlation with those diameters as well as those used in 17].
In free fall, an object will attain a constant terminal velocity at which the net gravitational accelerating force equals the resisting upward drag force [9].
