1. Water at 800?C, 15 MPa is flowing through a heat exchanger giving off energy to come out as saturated liquid water at 15 MPa in a steady-flow process. Find the specific heat transfer and the specific flow exergy the water has delivered.

2. A rock bed consists of 6000 kg granite and is at 70?C. A small house with a lumped mass of 12 000 kg wood and 1000 kg iron is at 15?C. They are now brought to a uniform final temperature with no external heat transfer by connecting the house and the rock bed through some heat engines. If the process is reversible, find the final temperature and the work done in the process.
