← HistoryWater lifting using a saqiya was vital in maintaining the Mughal Shalimar Bagh of Kashmir; which risk increased during extended freezing temperatures?
A)Gearbox cracking due to ice wedging✓
B)Reduced evaporation from reflecting pools
C)Pietra dura inlays shattering rapidly downward
D)Decreased irrigation efficiency overall locally
💡 Explanation
Icing increases risks to the saqiya's operation; the volumetric expansion during the phase change of water causes ice wedging in confined spaces like a gearbox. This is because the pressure rises substantially, therefore gearbox cracking rises rapidly as a risk; rather than reduced evaporation from pools.
