← ScienceWhich outcome occurs when fluid approaches a stenosis?
A)Pressure decreases; velocity increases✓
B)Turbulence decreases; viscosity increases
C)Density increases; Kinetic energy decreases
D)Temperature decreases; Reynolds number decreases
💡 Explanation
The Venturi effect explains this; the constriction decreases the flow area. Velocity increases due to mass conservation using the continuity equation, which increases the dynamic pressure component; therefore, static pressure drops rather than increases or kinetic energy decreasing.
