Saturated liquid water is heated in a heat exchanger until it exits as a saturated liquid vapor mixture. Hot oil is used to heat the water. The hot oil enters the heat exchanger at 150
C and exits at 40 C. The mass flowrate of the hot oil is 11 kg/s and has a specific heat of 2.2 kJ/kg-C. The water enters the heat exchanger at 25 C and 100 kPa. The water leaves
the heat exchanger as a saturated liquid vapor mixture at 100 kPa. The mass flowrate of the water is 1.5 kg/s.
What is the enthalpy of the water at the exit of the heat exchanger in units of kJ/kg?
