← ScienceWhich outcome occurs when cryogenic fluid leaks from a pipe?
A)Rapid gas expansion and cooling✓
B)Pipe material tensile stress increases
C)Increased fluid pumping efficiency
D)Pipe wall temperature remains constant
💡 Explanation
Rapid expansion and cooling occurs because adiabatic expansion of the leaking fluid causes a drop in temperature during isenthalpic expansion. Cooling results, rather than heating, because energy is lost by the expanding gas, therefore some turns into solid or lowers by energy.
