5500 kg/min of an ideal gas (Cp = 7/2, MW=36) at 460 °C is used to superheat saturated liquid water to 200 C. This reduced the gas temperature to 180 °C while a heat loss of 80 kJ /kg of steam was found. If all processes take place at atmospheric pressure, determine the generated entropy (W/K) provided that the surrounding temperature is assumed to be 30°C. Then, decide on the possibility of such a process.

5500 kg/min of an ideal gas (Cp = 7/2, MW=36) at 460 "C is used to superheat saturated liquid water to 200°C. This reduced the gas temperature to 180 °C while a heat loss of 80 kJ /kg of steam was found. If all processes take place at atmospheric pressure, determine the generated entropy (W/K) provided that the surrounding temperature is assumed to be 30°C. Then, decide on the possibility of such a process. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
