The fraction of condensate that flashes on release depends on
Answer: D
Correct answer: the difference in saturation enthalpy between the two pressures
When condensate is released to a lower pressure it is hotter than the new saturation temperature, and the surplus enthalpy boils part of it off: \[ x = \frac{h_{f1}-h_{f2}}{h_{fg2}}. \] The fraction is a property of the two pressures alone, so the mass released and the pipe size change how much flash steam there is, not what proportion flashes.
