SUMMARY
The discussion centers on the influence of pressure energy on fluid flow in a tube with varying heights, specifically analyzing a scenario where an incompressible fluid moves from a height h1 to a height h2 (where h2 > h1). The net work done on the fluid is expressed as P1V1 - P2V2, where P1 and P2 are the pressures at points a and b, respectively. The negative sign in the equation indicates that the pressure at point b (P2) opposes the fluid's motion, necessitating work against gravitational forces. This establishes that pressure energy plays a critical role in fluid dynamics within vertical tubes.
