18.0 m³ /s of methane are mixed with 10.0 m³ /s of isobutane in a test of a new furnace gas. The mixture is preheated before being ignited by passing it through an adiabatic, isobaric heat exchanger.

The second fluid in the heat exchanger is condensing steam at 200.°C flowing at 8.30 kg/s. The steam enters as a saturated vapor and exits with a quality of 21.0%.

The gas mixture enters at 20.0°C and exits at 150.°C (Figure 12.13). Determine the entropy production rate of the heat exchanger.
