5. Air flows through an insulated device, operating at steady state, exhausting into the atmosphere (pressure 100 kPa, T = 300 K). Following information are supplied for the inlet and exit. Inlet: A = 0.1 m2, V = 10 m/s, p = 300 kPa, and T = 400 K; Exit: A = 0.1 m2. Hide Details (a). Determine the rate of entropy generation in the system's universe. kW/K Enter answer as a decimal number (3.14, 5.0, -2.78, 5, for example) (b). To eliminate the entropy production, you start tinkering with the exit area. Determine the exit area in cm2 that will completely eliminate any entropy generation. cm? Enter answer as a decimal number (3.14, 5.0, -2.78, 5, for example) (c). Which of the following options best describes the new device you created?
