Critical velocity is defined as the speed at which a falling object reaches when both gravity and air resistance are equalised on the object. The other way of defining critical velocity is the speed and direction at which the fluid can flow through a conduit without becoming turbulent. Turbulent flow is defined as the irregular flow of the
