SUMMARY
The discussion centers on the presence of a negative sign in the integral expression (z2 - z1)dA, which represents a volume element in fluid mechanics. The negative sign arises because z1 is defined as the larger value, indicating that z1 and z2 are negative numbers when considering z=0 as the fluid surface. This convention ensures that the force acts in the positive z direction, clarifying the physical interpretation of the integral.
