Science

Which consequence results when a sudden expansion occurs in a pipe carrying high-speed fluid, specifically considering its turbulence?

A)Increased static pressure downstream immediately
B)Decreased kinetic energy uniformly throughout
C)Laminar flow re-establishment promptly
D)Cavitation risk suppressed significantly

💡 Explanation

Increased static pressure occurs because flow separation and stagnation happen creating turbulent kinetic energy dissipation within the expansion. This causes less kinetic energy. and therefore more pressure rather than lower static pressures or immediate laminar flow since turbulence dominates after pipe expansions.
