← ScienceWhich mechanism increases energy dissipation in pumped hydro storage?
A)Turbulent kinetic energy cascade✓
B)Enhanced laminar boundary layer drag
C)Reduced form drag coefficient
D)Increased static pressure recovery
💡 Explanation
As the high-speed turbine discharge transitions to the tailrace, kinetic energy breaks down via the turbulent kinetic energy cascade into smaller eddies, because momentum disperses to random fluctuations. Therefore, total energy dissipates rather than being efficiently converted to potential energy during filling.
