Saturated liquid water is heated in a heat exchanger until it exits as a saturated liguid 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 10 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. It is also know
that the enthalpy of the water exiting the heat exchanger is 1718.2 kJ/kg
In the question that follows, select the answer that is closest to the true value
What is the quality of the water at the exit of the heat exchanger?
O 0576
O 0 933
O 0 862
O 0 791
