Free flow speed
WebThe free flow speed (FFS) is defined as speed that occurs at a point, when the flow density is zero. For the ideal capacity of free flow speed for freeways: The highest … WebThe flow velocity u of a fluid is a vector field which gives the velocity of an element of fluid at a position and time The flow speed q is the length of the flow velocity vector [3] and is a scalar field. Uses [ edit] The flow velocity of a fluid effectively describes everything about the motion of a fluid.
