A 4 kg/s of fluid enters a device with an initial pressure of 700 kPa, initial velocity is 70 m/s and the fluid initial density is 3 kg/m3. The fluid leaves the device at 182 kPa,150 m/s and 0.80 kg/m3. The heat loss from the device is 19 kJ/kg and the work done by the fluid is 232 kW. Determine the change in internal energy, in kJ/kg
