A nitrogen line, 540 R, and 75 lbf/in.2, is connected to a turbine that exhausts to a closed initially empty tank of 2000 ft3, as shown in Fig. P6.119. The turbine operates to a tank pressure of 75 lbf/in.2, at which point the temperature is 450 R. Assuming the entire process is adiabatic, determine the turbine work.
