Which behavior appears in fluid flow systems when increasing velocity through a narrowed constriction?

A)Onset of flow choking
B)Decreased turbulence kinetic energy
C)Decreased Reynolds number magnitude
D)Increased pressure drop recovery

💡 Explanation

Flow choking occurs because the velocity cannot exceed the sonic limit at the constriction due to the converging-diverging geometries in the system. Therefore, mass flow rate saturates, rather than increasing, while pressure drops continuously.
