Physics
Saturated liquid water at 10.0 mpa is throttled through a partially open valve (isenthalpic process) and discharged into a tank at a pressure 0.1 mpa adiabatically, aergonically, and without any change in its kinetic or potential energy. (note: when the pressure on saturated liquid water is suddenly reduced in an adiabatic aergonic, steady flow process, part of the initial liquid is very quickly converted into a saturated vapor at the lower pressure, with the vaporization energy (heat of vaporization) coming from the remaining liquid. the resulting vapor is called flash steam because the liquid appears to “flash” into a vapor as it expands into the low pressure region). determine:
the exit temperature of the flash steam
the amount of flash steam produced (quality)
