A nitrogen line (300K, 0.5 MPa, V-hat = 0.177921 m3/kg, U-hat = 301.38 kJ/kg, H-hat = 310.276 kJ/kg) is connected to a closed, initially evacuated tank of 49 m3. The turbine operates to a tank pressure of 0.5 MPa at which point the temperature is 250K (V-hat = 0.147817 m3/kg, U -hat = 183.89 kJ/kg, H-hat = 191.281 kJ/kg). Assuming the entire process is adiabatic, determine the turbine work to the nearest 1 decimal place (in kJ/kg).
