In fluid mechanics, when analyzing the forces acting on a submerged curved surface, it is essential to determine the vertical component of the resultant force exerted by the static fluid. This force is directly related to the weight of the liquid that is vertically above the curved surface. The proof of this concept is derived using the principles of hydrostatics.

Consider a curved surface submerged in a fluid of density \( \rho \), where the pressure at a depth \( h \) is given by the hydrostatic equation:

\[
P = P_0 + \rho g h
\]

where \( P_0 \) is ____ ____ ___ ________ _________.
