Carbon dioxide flows steadily at 1 kg/s through a device where the pressure, specific volume, and velocity of the gas are tripled according pVn = C. The inlet conditions are p1 = 200 kPa, v1 = 0.4 m3/kg, and v1 = 100 m/s. Determine (a) n is -1; (b) the initial and final temperatures 423.39k and 3810.53k; (c) the change of enthalpy is 2560.67 kW; (d) the power is 4x10^4 watt; (e) WHAT IS THE the heat transfer? please explain, thank you!
