A gas stream with a flow rate of 1000 mol/min leaves a reactor at T = 450

Question:

A gas stream with a flow rate of 1000 mol/min leaves a reactor at T = 450 K and P = 10 bar. For the next step, the temperature of the gas must be reduced to 300 K, but the pressure of the stream isn’t very important. Consequently, a turbine is being placed after the reactor, to obtain some work, but the turbine must be designed to have an actual outlet temperature of 300 K. Find the turbine outlet pressure and the work produced for each of the following cases. In all cases, the gas has C_P* = 40 J/mol · K.

A. The gas is an ideal gas, and the turbine is reversible.

B. The gas is an ideal gas, but the turbine efficiency is 80%. Find the turbine outlet pressure and the work produced.

C. The turbine is reversible, and the gas follows the equation of state.

D. The turbine efficiency is 80%, and the gas follows the equation of state.
