Air at 0.101 MPa and 50.0°C is saturated with water vapor. It is to be aergonically heated to 80.0°C in a steady flow, isobaric process by putting it in contact with an isothermal reservoir at 100.°C.
Determine the heat transfer and entropy production rates per unit mass flow rate if
a. The presence of the water vapor is ignored.
b. The presence of the water vapor is considered (as an ideal gas).
c. Determine the percent error in the answer a due to the effect of the water vapor.
