in displacement ventilation, cooler supply air is introduced at a low velocity at the floor level, displacing the warmer room air and creating a zone of fresh, cool air at the occupied level. source: businessweek in this sentence, velocity means: degree of hotness or coldness of a body or environment distance travelled per unit time in one direction difference between value of a property and claims against it elevation above sea level or above the earths surface

Answer

Brief Explanations:

Velocity in physics is defined as the distance travelled per unit time in one direction. In the context of displacement - ventilation, it refers to how fast the cooler supply air moves.

Answer:

distance travelled per unit time in one direction
