1. Determine the entropy production rate as 5.00 lbm/s of saturated water vapor at 14.696 psia is condensed isothermally and aergonically in a steady flow, steady state process to a saturated liquid. Ignore all kinetic and potential energy changes. Explain the significance of your answer.
2. Air is throttled from 1.00 MPa and 30.0°C to 0.100 MPa in a steady flow, adiabatic process. Assuming constant specific heat ideal gas behavior and ignoring any changes in kinetic and potential energy, determine
a. The change in flow stream entropy.
b. The entropy produced per kg of air flowing.
