Geometric stresses above the head, static pressure, dynamic pressure head is the mutual conversion. In the still of fluid, only geometric pressure head and pressure head, and geometric head and static pressure head and keep a constant. When the fluid flow, fluid not only geometric head, static head, and the dynamic pressure head. To increase the dynamic head, is by the static head turned. In the process of fluid flow, if there is no resistance head, or neglected, then, geometric head, head, head moving sum will keep a constant. They can be from one form into another form, but the sum is unchanged. This is a manifestation of the law of conservation of energy,
