EML3100 Exam 3
l.The high-pressure water at 2MPa, 200°C, is throttled into a ash evaporator chamber, which
forms liquid and vapor at a lower pressure of 500 kPa. Find the temperature and quality of water
in the flash evaporator chamber. Hint:
A sealed rigid vessel of 2 m3 contains a saturated mixture of liquid and vapor R134a at 10 C. If it is heated to 50 C, the liquid phase disappears. Find the
pressure at 50 C and the initial mass of the liquid.
Process: constant volume and consta
