Question:
Potassium, an alkali metal, enters a condenser in the vapor phase with a mass flow rate of 0.02 kg/s and at a temperature and pressure of 1370 K and 0.4 MPa. It exits as a saturated liquid at 0.2 MPa. Calculate the rate of energy transfer as heat from the condenser in kW using Appendix A.11 for data.
