8- A working fluid enters a steady flow system with a velocity of 30m/s and leaves at 140m/s. The mass flow rate is 9 kg/s. The properties of the fluid entry are 13.8 bar, 0.122 m3/kg, and internal energy 42.2 kJ/kg, and exit properties are 1.035 bar, 0.805 m3/kg and internal energy 208 kJ/kg. Determine the work transfer in kW from the system (2565 kW)
