Velocity triangle

Velocity triangle

The velocity triangle is the vectorial representation of kinematic movement. A vector is a directional magnitude. This relationship is illustrated in the velocity parallelogram of a liquid particle.

Flow angles in the velocity triangle

Angle α between v and positive u direction ("absolute angle") Angle β between w and negative u direction ("relative angle")

The position of one velocity triangle in relation to another velocity triangle does not indicate whether the flow velocities plotted on these triangles are in fact situated in the same positions in relation to each other in the actual flow.

The absolute velocity of a liquid particle may be divided into axial, radial and peripheral components.
