Water flows steadily through a section of piping in a heat exchanger at a constant pressure of 1.5 bar, entering as a vapor and exiting as a liquid. One side of the pipe is maintained at 400K and receives 20 kJ/s of energy by heat transfer, while the other side of the pipe is maintained at 800K and rejects 40 kJ/s of energy by heat transfer. Is this process possible, impossible, or indeterminate from the information given
