A nitrogen line, 540 R, 75 lbf/in2. is connected toa turbine that exhausts to a closed, initially empy tank of 2000ft3. The turbine operates to a tank pressure of 75 lbf/in2, at which point the temperature is 450 R. Assuming the entire process is adiabatic:
Calculate the work of the turbine assuming constant specific heat (variable specific heat is 47249.68 Btu).
