A fluid with a pressure of 820 kPa, specific volume of 0.30 m/kg and a velocity of 150 m/s enters a device. The work done by the fluid is 460 kJ/kg and the heat loss due to radiation is 28 kJ/kg. The exit condition of the fluid are 130 kPa, 0.82 m/kg and 320 m/s. Determine the change in internal energy.
