The Velocity head is a means of describing the pressure at a point due to the velocity of the moving liquid. A moving liquid has momentum. This momentum has a force at all points in front of the moving fluid. This is referred to as the velocity head.
The velocity head represents the kinetic energy due to the motion of the liquid.
Another way of describing it is by imagining it as the pressure the fluid would have at a specific point if the moving fluid is suddenly stopped.
where h is the velocity head,
v is the velocity and
g is acceleration due to gravity
