← ScienceWhich outcome results when a horizontal pipe exhibits reduced diameter?
A)Fluid velocity increases; pressure decreases✓
B)Fluid viscosity increases significantly rapidly
C)Fluid density dramatically increases locally
D)Fluid temperature sharply decreases briefly
💡 Explanation
Fluid velocity must increase due to the Continuity equation; as diameter decreases therefore static pressure drops, matching Bernoulli's principle for incompressible flow, rather than temperature or density changes, which are minimal in this subsonic constriction.
