Static head is defined as what in a fluid system?

Explanation:
Static head is the pressure produced by the weight of the fluid column above a reference point, due to gravity. In a fluid column, pressure rises with depth according to P = ρ g h, where ρ is the fluid density, g is gravity, and h is the vertical distance of the fluid above the point. Expressed as a head, this same pressure corresponds to a height h_p = P/(ρ g) of fluid. So the static head represents the hydrostatic pressure from the fluid’s elevation, independent of any fluid motion. It’s not atmospheric pressure, not the pressure difference across a valve, and not the outlet pressure.
