← HistoryWhich phenomenon explains efficient water transport by shallow Mughal garden canals?
A)Surface tension resists evaporation losses
B)Capillary action overcomes friction✓
C)Coanda effect accelerates flowrate
D)Hydrostatic pressure reduces resistance
💡 Explanation
Capillary action wicks water along the canal bed because adhesive forces exceed gravity and friction, therefore thin sheets of water move efficiently, rather than experiencing higher drag in a deep, narrow channel.
