← HistoryWhich consequence resulted when Medieval aqueduct channels calcified?
A)Waterborne disease transmission increased
B)The structure became seismically unstable
C)Water flow capacity decreased✓
D)Thermal regulation became inefficient
💡 Explanation
Aqueduct calcification increases hydraulic roughness, causing increased frictional pressure drop because mineral deposits narrow the channel. Therefore, flow rate diminished due to increased resistance, rather than changes in water purity or stability.
