Understanding Hydroelectric Draft Tube Functionality

The poster's lack of understanding about how hydroelectric draft tubes work, specifically regarding pressure increase and kinetic energy conversion, indicates a knowledge gap. The draft tube's purpose is to prevent backflow and increase the effective pressure head of the turbine, but the poster's intuition about suction effects and pressure usage is incorrect. Clarifying the functionality and resolving the apparent contradictions is necessary.
