power plants uses a diffuser in one of its modules to discharge heated water vapor throughout a steady state process. The diffuser is not well isolated and losses 1.5 kJ/s of heat to its surrounding. Water vapor enters this diffuser at 700 m/s, 200°C and 1 MPa, and discharges to a chamber which pressure is about 2 MPa. The diffuser wall has an average temperature of about 240°C during its operation. If the flow rate of the diffuser is 0.25 kg/s, and we assume the process of the diffuser is internally reversible and changes in potential energy is negligible, determine the temperature and velocity of the working fluid at the diffuser discharge.
