Propane at 350 degrees Celsius and 600 cm^3/mol is expanded in a turbine.  The exhaust is atmospheric.  What is the lowest possible exhaust temperature?  How much work is obtained?  You may assume Ideal gas behavior and heat transfer is negligible to surroundings.


I haven't gotten too far but I would like someone to confirm what I have done so far is correct, I went straight to finding the work done which by using a form of Bernoulli's is W/n = integral vdP to find the first pressure I did Ideal Gas Law P1=(350+273)*n*(8.314)/(600cm^3/mol) to get a specific Pressure(the problem didn't give any mole information or mass) Then I did the integral and found Work/mol but I am getting an extremely large number for the initial pressure (8.633*10^6 Pa). I'm a little iffy on if I can actually use a specific pressure here can anyone help please
