← ScienceWhich outcome follows if a closed-loop organic Rankine cycle encounters subcooled temperatures?
A)Increased condenser heat transfer efficiency
B)Cavitation occurs in the feed pump✓
C)Thermal runaway increases the turbine output
D)Working fluid remains entirely in vapour
💡 Explanation
Cavitation risk increases because decreased fluid temperature drops the vapour pressure, therefore liquid can flash to vapour at the pump inlet, rather than liquid being compressed leading to efficient stage-one transfer.
